I think the easiest solution is just to make stalemate a win so king + wildebeast can win against bare king.
I don't see any need to change the promotion rules though. Even if you don't change stalemate, promotion is not an issue. You are only forced to promote to wildebeast if you do not have a queen, in which case you promote to a queen and can checkmate easily. The only other case I see is the unusual position where you don't want to promote to a queen because that would stalement immediately, but since the horsemen promote on the 7th rank I don't think that is possible.
