Allow one player to walk through walls?

Hey folks, I'm doing some prep for a Halloween one-shot where one character is likely to spend some time as a ghost. Is there any way I can allow them to move through dynamic lighting barriers without disabling it for the entire map (and thus every player)? I suspect the answer is no, but would be good to have confirmation either way (since it could come up later for stuff like characters turning ethereal, or even single casts like dimension door, etc). Thanks in advance!

Beyond giving that player the GM role, nope.

It could be emulated with scripts. Token Mod can move a token one square to the [left,right,up,down], for example, and I think that ignores dynamic lighting restrictions, though I've never tested. Dynamic Lighting Tool can turn on and off barrier possibility with a macro. But unless your game is created by an active Pro user, this is not possible.
