Yes, you'll be able to reuse the characters if you delete them (using same name)...at least I could :P
To move a stuck character out of a zone log in on another, unstuck one and type:
#movechar <character_name> <zone_you_want_them>
e.g.
#movechar Monrezz sleeper
to move "Monrezz" into Sleeper's Tomb.
Hope this helps
