Help with spell sage concept

[Uwotm8]

I'm looking for other wizards who have dabbled in the divine. I don't want an Elminster, though. He's boring and been done. I'm thinking of kind of having him be 'out of it' a lot due to the spell sage's ability to cast off other spell lists is supernatural. Maybe kind of a hippie - "it's all connected, man." Anyway, what ya got?

• I've no idea what I'm doing, but it seems to work all the same.
• Anything you can cast, I can cast better. Or too, anyway. Sort of.
• I will become the grandmaster wizard of ALL magic!

Was that the sort of thing you meant?

More the grandmaster of all magic but someone who pursues the essence of magic for more of the same understanding that enables them to cast cleric spells among others. That's more the driving goal, though. I'm looking for a personality to wrap around it but don't really have a cast of characters in my head to pull from like I do with strictly arcane/magic items/hoard all the tomes style wizards.
