Online Chess With Illegal Moves Allowed

Hello, 

Me and my pal have invented this game that's based on chess and we'd like to play it online together but it involves moves that would be completely illegal in chess, so we would need a platform that lets us perform any move. Ideally it would be great if the platform also counted and maybe kept track of the moves. Does anyone know of anything that could work for this?

Thanks

Unfortunately there will be many times where kings are in check ^^' there may even be positions where the kings are right next to each other.

Oh that's great! But so using this method wouldn't let us see each other's moves in real time then would it? We would have to send each other the FEN or tell each other the move after each move? Because thats what I was trying to avoid. But I suppose if we dont find anything else that will have to do...
