The queen needs to be one more square over to the right on the first one (or replaced with a rook), won't let me re-edit it.

good call on the second one 😞
Mabye it works if there is a white bishop on D1, then bishop can't move.
In that case, a possible scenario could be black bishop was on c2 and went to b3 check, then king moves, mate.
That would create a situation where there were two mates however, bXb c3# and k-c5#.
Hmm, back to the 'Drawing' board, so to speak🙂
I still like my solution, it follows the original rules to the letter.
