As a matter of interest did you get up and down from the bunker? I ask because a) I'm not a good bunker player and (b) If I played the lie you described the ball could well go anywhere with the sand the least worst result.

Therefore I'd have been tempted to take my medicine, declare the ball unplayable and take it back enough to give myself a manageable little pitch / lofted chip.

That way I trade a one shot penalty to avoid something potentially worse.
