Project L
Can I add the Ghost Piece expansion to the retail base game?
Several owners who play the two together agree, with no official ruling and no dissent.

Yes, in practice. Owners who have combined them report it works, and the compatibility note concerns the puzzle material rather than a rules barrier. On the retail base, the piece count is the real limit, not the puzzle thickness.
