On the other hand it seems to be possible to save a pawn on
the *left* hand side by replacing Pa4/a5 by a single bPb5
(which dare not move because of Ba4-c6):


This might also make it worth another look at Andrew's suggestion
"try to remove bPh4 & move sPg3 to h3" (after 1 gxh3+ Kxh3?! 2 Kb7,
Black has a passed b-pawn, and the Black Bishop reaches b6 a move faster
via a5); but the outcome is still not clear to me and the extra analysis
still seems to high a price for saving one Black pawn.
