Interesting variant with innovative promotion rules.
They might be innovative, but it seems to me they are also pretty useless. I cannot conceive any situation where you would decide to take the Pawns. At best it would delay your win, because you would have to promote the new Pawns all over again.
If you promote in an approximately equal situation, promotion to a piece would give you an immediate advantage, which you can use to force checkmate, or gobble up enemy Pawns. If you are behind in pieces Pawns are just a liability, to be annihilated by the opponent's superior piece power. Promoting to a piece to restore the balance would at least allow you to hold on to the Pawns you already have.
