I would say at this point that it would all depend on the filming schedule for the Wives Club. At this point, they only have 10 episodes ordered. Depending on how much post-production is needed with that, they will probably have alot of the filming complete (particularly since they had originally anticipated that this would be ready for the Fall 2014 season).

Last year, during 3B, Megan Ory was able to be involved minimally with a couple of episodes, based on when her filming for her series (which is now cancelled) wrapped. And I think that has been true with other actors as well. So if Adam and Eddy want Joanna to be available, they might be able to make it work. (It helps that both Once and Astornauts will be on ABC.  makes the negotiations between the production studios a little easier).

but as you said, I wouldn't hold my breath. The script(s) would need to warrant the effort necessary to make the arrangments to have Joanna available.

Having said all of that, I would LOVE to see Ariel (and Eric) back.

And just for kicks, It'd be fun to bring in King Triton as a warlock on the hero side of the equation (there is a real shortage of male magic using characters).
