Thoughts on my chess varient

I created this chess variant where before the game starts, you can remove pieces from your opponents side. However, the catch is whatever piece(s) you remove, the point value, you lose that many minutes. Both players will have 10 minutes, so you can remove up to nine points of material from your opponent. I've played this with multiple people and seems to have little to no flaws. For example, one of my friends kept talking my queen and only played with a minute (given a queen is worth 9 points, you lose 9 minutes). But because I had more time, it became equal and some games I would just win the queen back. Can't say it's completely flawless cause people like Hikaru could just take a queen and play really well with a minute. Of course, no increment or delay is allowed. The point is to find the balance of how much material can I remove with still being comfortable on time and what pieces strategically should I remove while simultaneously also at a disadvantage. I can't find any flaws outside of possible GM levels, but I have been trying this with friends for a few years and yet to find anything to correct it on. If anyone finds an issue with this variant, please let me know. Does this actually sound like a fun variant or not? 

Who removes the pieces first? Does White remove Black’s pieces first, and then Black removes White’s pieces? And if this is the case, doesn’t Black have a slight advantage by being able to react to what White removes?

What about equivalent material losses? Surely, if this game were to be explored, there might be strategies that would make for perfectly matched boards. Maybe both sides would remove both queens, essentially making it a normal 1-minute Bullet game without queens. If this variant were to become popular, several “openings” would arise, where the games would essentially be regular ones with faster time controls, and without key pieces. Would this make the variant “boring,” considering that from that point on, it will simply be a regular game?

I like how this variant allows for two playstyles: people who want to risk their clock to make it easier to win, or people who may want to save some of that time, knowing that their opponent won’t have nearly as much. People would be thinking about whether to remove a piece, or to take the extra time and material disadvantage, and attempt to get their opponent to run out of time. Do you trust yourself with less time? It rewards both quick players and deep thinkers, each for their own reasons.

I think this variant definitely has a lot of potential, but I’m really curious to know how the above questions will be addressed!

Both sides would remove pieces at the same time, that's how I did it over the board, as of online, I would think it would be best to have a minute before the game for both sides to remove pieces and once both sides hit the confirm button, then it goes into the match and is revealed what was removed by the opponent. As of equivariant material, I think with many people playing it, it can lead to that, but hopefully a lot of variety will happen with people trying different stuff. Especially if your black, your main goal is making sure white doesn't have any immediate attacks and white your going to be looking for immediate attacks. I take the f file bishop and the g file pawn every time and usually will take one more minor piece depending on my mood. The idea being its easier to castle short, but that's very dangerous to. Another person I tried playing took the f and g pawn for an easy queen attack potential mate. I think it would strengthen a lot of middlegame tactics with a lot of players because you almost immediately go into a middlegame and worry less about not playing perfect theory in openings. As for it being boring, I don't think that's a fair question just because every one I know including myself finds regular chess boring at times and repetitive. Not to say its a good question and concern, I think that is a great concern, but sometimes chess is boring in general and it's very similar. I have no idea how to stop that problem without making the variant exotic which I have no intention to given I like the simple nature of the rules. Though with the fast and slow time control, my main concern is there is no solved way to guarantee way to be in a completely winning position immediately, not to say that will happen sometimes just because of what pieces are removed. But more often that not it's "balanced" with time being a problem or material being a problem.

Now that you got me thinking about it, a fail-safe idea I'm thinking of is whoever starts with more material on the board; if its a draw, that color wins (similarly to Armageddon in GM chess tournaments to white has more time, but if its a draw, black wins) so if there is a solved way with 8 or 9 points with minor pieces to guarantee a winning position, they will have to checkmate/win on time. Though not the greatest idea just because you could just remove a pawn and create a fortress, but even then that would still teach players how to stop fortresses and force players to learn fortresses if they realize their in a losing position and started the game with more material. Similarly to chess960, it throws regular opening preparation out the door which can be nice between 1800s and below just so you don't have to worry about playing into someone's opening preparation. There could be flaws with specific pieces being removed, but I haven't discovered any. But similarly to fog of war variant where you can lose your King in four moves in you don't protect your f pawn, the more you lose a specific way, the more likely you change what pieces to remove so you don't lose that way.
