Puzzle 2530

Similar to a previous post: can puzzle 2530 be changed to return a "good move, but you can do better" for Bb5+ from the following position?

Bb5+ move leads to mate in 2 (Kc5 Be3#) but results in outright failure on this puzzle.

I guess the puzzle just want the fastest checkmate possible :/
