The whole point seems moot. You don't need 3 Queens to checkmate, and using a second one against a bare King is already embarrassing. The worst case I can imagine in FIDE that has any practical interest is KQKP where you can draw with Rook or Bishop Pawn on the 7th rank when the promotion square is covered by King, and the attacking King is far away. The trick is that with a Bishop Pawn the King can step into the corner, in stead of in front of the Pawn, because when the Queen captures it it would be stalemate. And with Rook Pawns you can force the King in front of the Queen, but you cannot use that to approach with your own King, as this would be stalemate.

I think in Grand Chess KQKP with the Pawn only removed one step from promotion and the promotion square covered by its King is always draw, no matter what Pawn you have. And not because of stalemate.
