That would certainly give me a reason to play a Diviner (spellcraft granting ac like tumble idea). I think it's a great idea overall. So many reasons why many schools don't see PC members... this could help with that.

In PnP, though, Red Wizards also get Enhanced Spellpower (like heighten meta magic, raising the level-dependent spell variables), of their schools. Which would also be a nice custom feat on the robes... (tying the bonus levels to notoriety instead of Red Wizard PrC level would be an idea for here)

Circle Magic would be even greater but I realize that's even harder to do...
