I had an idea, as I was thinking of how Wizards seem to be so important in Golarion, of a setting where Sorcerers are the true/paragon arcane casters, with wizards being the ones trying to emulate sorcery with learning (and arcanists somewhere in between). I think the only changes really needed for this are giving sorcerers the odd-level spell progressions and wizards having it delayed, and giving sorcerers their bonus spells when they get their spell levels. Would anything else need to be done to wizards to bring them down, or sorcerers to elevate them, or would they be reasonably balanced that way? Or, are they balanced as is, and it would only take a change in flavor?
Also, since they don't need to be cloistered, would giving sorcerers 3/4 BAB and/or d8 HD be too unbalanced? I am going for a slightly different world flavor, but I don't want to screw balance too badly.
