I am not sure what exactly you propose, but I am pretty sure it won't work. Fairy-Max only promotes piece #1 (in the white promotion zone) and #2 (in the black zone). And it always assumes promotion is mandatory and changes piece #1 into piece #7, and piece #2 into piece #7 or #9 (the latter only if black does not start with a piece #7). Except in Grant Acedrex, which is sort of a hard-coded exception, where the Pawns promote to the piece that started on their promotion square. So different Pawns can promote differently there, but there still never is any choice to what a particular Pawn promotes to.
It is this no-choice limitation that is the show stopper. It is really deeply engrained in the way Fairy-Max works: moves are internally encoded by a from-square and a to-square, and no other info.
