Inverted Crazyhouse

I've had a bit of a go at crazyhouse but there's a few things I'm not so fond of, so I made up a variant which tries to modify crazyhouse.

The things I don't like so much are:

-Blundering pieces feels much worse because your opponent can then use them for drops.

-Checkmating is too easy.

So this version of crazyhouse would turn it on its head to try and fix these issues. The modified rules would be:

-Instead of being able to drop pieces & pawns you took from your opponent, you drop your pieces & pawns that have been taken as a comeback mechanism.

-To still incentivise capturing pieces, there is a 8-move "cooldown time" from having your piece taken to being able to drop them. On a board you can track this cooldown time by moving the pieces by the side of the board one square each move. You might want to slide them on all on a piece of paper to make this easier.

-You can capture your own pieces/pawns, if you do this you can use them as drop material after the cooldown time.

-To stop checkmates from being too easy, you can no longer drop pieces with check.

Does this seem like a fun variant?

Would it fix the issues I see with Crazyhouse?

Are these even real issues with Crazyhouse or are they just artefacts of me not having played it much?
