What about Callers? 
Those Summoners can use Summoning, and both black and white magic. They only lose white magic when it becomes too hard for them to focus on the other two branches of magic.

Callers are the same as summoners aren't they? At least the wiki is telling me this. If you want something a little different than the description in the OP then you're free to do it.

Yes. You may indeed have a Highwind character but be warned, you'll be Cid's kid.
