Variants that can be interesting

Hi, i don't play regular chess often but I have some ideas:
1) version where every player has 2 moves, or variant with 1 move, then 2 moves, then 1 (1-2-1-2-1-2....)
2) version where we can pick to play without one major figure (for example I am bad at regular chess, so if I play against some higher elo I would like to have the option to play without queen, rook, bishop, knight for my opponent
3) option with a bigger board, because for my chess on8x8 is a jam, and there is too much traffic in a small space, so if you could make a board that has 2 extra lines in the middle (8x10) or even 10x10 (you just add 2 pawns on the sides

I know version 1 has been played in France (Marseille I think)

Kind regards

and maybe version 4) team play where 2 players can use one team in a game. Each player can move only one move after his teammate. 4 players, 2 play for the white and 2 for the black side. No communication between team players.

This sounds fun, but of course it's impossible to enforce "no communication between players", people can be in the same room/on a zoom call/etc. Of the ones you proposed this is my favorite (also larger board sounds fun lol)
