Remember Gibson already offered a Pearly Gates Reissue, so the two finished mentioned above might be the closest you'll get on a used Reissue or M2M... unless new Gibson (Cesar) works with Billy G to do another round of PG in the Murphy Lab, etc.
IIRC @mikeslub has both a PG Reissue and a Burnt Wheat. You can probably search the LPF backlog and find them to compare. [He may well have a Slow IT Fade as well, those are more common, so no problem finding them].
