Something like Sha'ir X / Nar Demonbinder 1 / MT Y.
Sha'ir = gen or genies , Efreet (genies) could be semi-demons easily.
I suppose Sha'ir / UrPriest / MT could be OK
... not sure about the fluff on this one.
Certainly not for the historic real life inspiration.
... It has already been decided that the Sha'ir is a dual Divine/Arcane class so please don't argue that point ...

... What I need is a RAW justification for saying Mystic theurge would advance my spells twice per level. Any Ideas? Thanks!

Gestalt Wizard // Archivist as one type of mechanics
and Cleric // Sorceror as the other type of mechanics,
you can put Sha'ir somewhere in the middle
and go a pseudo-gestalt/double Sha'ir with the MT levels.
Yeah sure, wtf you come up with, is no problem for houserules.
Just understand you're doing Homegame + Tier 1s + shenanigans.
