All of these ideas are great from a gaming rules perspective - each sines in slightly different ways. But do any of them actually present a "specialist"? It seems that by prohibiting two schools, it forces the player to actually choose more spells from their professed speciality.
By getting to choose spells from any school, the Universalist has a strong advantage as shown by all the comments here. I'd rather see a weakening of the Universalist's special abilities (as they're really powerful) than making the specialist stronger. The two school prohibition, seems like a perfectly good trade-off. Don't think of it as a punishment, try something like: "If I have the cake, I can't have the ice cream." Each day you choose to have the special ability OR you can choose to memorize a spell (or more) from those two schools.
I like flavor.
