What in the world makes anybody think Palin wants back in the “GOP room”? Illegal immigrants, wolves and gay clergy are treated better than the Palin family by the GOP.
Simply “letting her back in the room” solves nothing, anyway. The establishment wants to marginalize/ignore her or co-opt her. (And anyone else like her, this isn’t a Palin-specific thing.)
What they won’t do, under any circumstances, is actually turn over control to her. Without control, it’s just a means to co-opt and perpetuate the establishment machine.
