Later edition of the same non-fiction book attributed to a different editor name

[Valentine]

I wonder if another librarian would perhaps mind advising… if a small museum published a book about their museum and attributed it to a named editor, and then some years later published a subsequent edition attached only to the name of the museum publications committee (as it was no longer edited by just one person, and I imagine museum staff changes mean the people involved can vary) - is it possible/acceptable to add a new edition where the author is the museum publications committee, as opposed to a named person, and therefore differing primary author? Or would it have to be created as a new work entirely? Thank you very much for any advice.

* Edit: seems this is a tricky one, but I can see a similar past situation here having to be added as a separate work, so I’ll stick with what others are doing.
