The only issue I have with a Fring spinoff is that we're already getting into a lot of his backstory right now, and he doesn't have an arc that we can go into post-BB.
Not to mention that even if that happened there'd be no way around getting different actors to play him and anybody else that may be part of the universe already that we know. At that point the aging issue would be even worse that it is now.
I'm just not sold on a Fring spinoff
