Unfortunately, the black bishop can't legally (retro analysis) be on g1 on White's turn. This double check wouldn't work.
If you meant the opposite, which implies Bh4 moving to g3 with check as the last move leading up to this suggested position, then after 1.Kxg3 there is no followup for mate in one by Black. Which means it is also incorrect.
