Given that Black's to move, I'm wondering if it's possible for either side to get a win from this position. A Black Queen (the promotion that actually took place instead of this position) is a forced win for Black with careful play, and Marshall vs. Marshall is almost certainly a draw, but the similar yet different power of the pieces here makes it a complex problem.

user15415: Since my Stockfish fork for fairy chess variants already supports Almost Chess, I added Sort of Almost Chess with both sides having all promotion options (which is what you seem to imply in your question).
I ran a search on the given position up to depth 50 with the commands below:
setoption name hash value 1024
setoption name multipv value 30
setoption name UCI_Variant value sortofalmost
position fen 7Q/8/6K1/8/8/1k6/6P1/c7 b - - 0 1
go depth 50

The results below state that white is winning (latest in 23 moves) irrespective of black's next move. Going through some of the variations in the output it seems relatively clear that the chancellor has no way to give a perpetual, so white is able to advance the pawn and finally either promote or force the exchange of queen and chancellor.
