What a fascinating ending. I don't think black can win with the obvious move to go after the b-pawn with 1....Kc5- white has counterplay with 2.g4:

1....Kc5? 2.g4!

And black has a decision- take at b6 or take at g4. I think if black doesn't take at b6, then white wins:

2....hxg4?? 3.h5! Bc8 4.h6 and white will queen either the h-pawn or the b-pawn.

So, at move 2, black has to play

2....Kxb6 3.gxh5 Bc8 4.Ke2 and white will exchange off the last black pawn with f3 at some point.

This basically leaves only one move to try to win, and I think it does:

1....e3!!

This forces white to either take at e3, or play f3- but either move solves black's main problem- having a pawn left to win with:

1.....e3 2.fxe3 Kxe3 and now white can't play 3.g4 since black just captures at g4 and the white king can't cross the f1 or f2 squares to prevent black from queening at g1 with check- this also means that b7 is no counterplay either since black just queens at g1 with mate otherwise. This leaves

1.....e3 2.f3

But now the white king can't approach the e-pawn immediately, so blach has

2....Kc5

And now white can play b7 forcing the bishop to release control of e2, but then the black king just returns to d4 to protect the e3 pawn, and the bishop can control the white pawns long enough to win- in total:

1....e3 2.f3 Kc5 3.b7 Bb7 4.Ke2 Kd4 5.g4 hg4 6.fg4 Bc8 7.g5 Bg4 8.Ke1 Bh5 wins.
