Using that logic would also mean Armadyl would possibly take back all of the clan citadel islands which aren't in-use as well. I doubt he'd do that, becasue he probably doesn't really have a need for them yet.

On the grounds of claiming and roleplaying there...I would advise against it. It probably isn't even known/accessible to most characters, and claiming stuff is bologna anyway.
