My idea of a variant maybe called liar's chess

First of all let me just say that I realize there is a game called liar's chess where you can take back your moves, but I think a more fitting name for that variant would be cheaters chess, and then my variant could use the name liar's chess, but until some Internation Chess Committee changes the names, I will be looking for something more fitting.

The rules of the variant I imagined would look something like this:

• You only see your opponents pieces location but not what type of piece it is (so just as a blank)
• You get to set up your starting pieces position as you want, but only in your first dedicated 2 rows
• The game goes until someone takes their opponents king (actually takes not just mates, since you won't know if it is mated)
• You can move your pieces however you want as long as it is a legal move for at least 1 normal chess piece
• After a move, the opposing player can call "liar" on the move that was made, which would mean he doesn't belive that the moved piece can actually legally make the move that was made. After that the player who made the move reveals what kind of piece it actuall is that he moved. If the player calling "liar" was correct, and indeed it was an illegal move, the one who made the move will have to take back his piece, and basically rewert the move, if he was not correct and the move was legal, the player who made the move gets to move again (This last part can be changed, but the main idea is a punishment/reward)
• You do not have to call liar, only if you want to on a move
• If you take a piece you do not get to see what kind of piece it was

Just to elaborate a bit further, the main idea is that you play without knowing which piece is which of your opponents, and you get to lie about what your pieces are. For example I move my pawn as if it was a knight, and if my opponent thinks it is not actually a knight, he shouts liar, I need to show him what piece it actually is and because indeed it wasn't a knight, I need to move back, and now he knows thats a pawn (if he can remember later).

I think it would be kind of fun, includes lot of mindgames, some memory, perhaps a bit of deception. In real life you could use pieces that are all shaped the same, but have faces only on one side, so only you would see yours, and when the opponent calls liar you just show the face of your piece, then turn it back if the opponent wasn't correct. Online it would obviously be easy to program since the computer would know which piece is which. After the game you could rewatch all the moves with the pieces revealed for added fun.

The whole idea is based on stratego and the card game we called liars in middle school, and I would like to know what do you guys think about it?
