Variant request: piece capture and redeploy

First time posting so if this is in the wrong place let me know

I want to create a new variant.  I was wondering if some devs can help make this a reality as the ability to put captured pieces back on the board isn't an option yet when creating your own variant

In shogi when you capture your opponent's piece, on your next turn or any turn after you can put that piece back on the board and use it like any of your other pieces.  
I've played this variant with chess pieces over the board (pre covid) and its such a fun, tricky and quick-paced variant to play with chess pieces.

we have played with the following rules before:
1, Placing a piece on the board cannot give an immediate check / mate
2, pawns cant be placed on the 8th rank (if you are white) or 1st rank (if you are black) to promote.  but for lols you can put them on the home rank.  fun for blocking pesky immediate back rank mates
3, you CAN place a piece to block a check
4, if you capture a promoted piece you can drop it as a promoted piece

5, optional rule:  you can "wound" your pieces by attacking your own pieces.  you can then drop that wounded piece once it's "healed" anywhere on the board the next turn. 

I hope this sounds fun and I hope with your support we can turn this into an official variant version on chess.com
if it is or if this variant is elsewhere please let me know

or if someone can code it then it would be super fun to play a game thankyou 

That is essentially CrazyHouse, with a couple of exceptions.

Brilliant thankyou 
im new to chess.com so didn’t see this on the variant page

i see on the custom variant page you can chose standard black hole chaturaji chaturanga 960 decker gothic horde and xxl chess 

do you know if there’s a way of choosing crazy house ? 
because adding any capture would pretty much get me my variation.
And it would be so much fun mixing it with the other variant rules like fog of war  or atomic - that would be a messy game
