Further to my comments earlier.It is entirely up to the club. But I think it inadvisable to have two Local Rules in force, so I would have the 6" rule for all play.
If bunkers are not in a absolutely disastrous condition, clubs should simply adopt the Preferred Lies (6") rule or Play it as it Lies for a ball in a bunker.
If one or more bunkers are a disaster area then I would suggest the the affected bunker(s) are designated as GUR and marked individually with a GUR (or GUR/NPZ) sign.
A player cannot have 3 options. ie Play as it Lies, PL or GUR.
It is either PaiL or PL
or PaiL or GUR.
