Effortless Trickery alternatives?

[Utopian]

Is there any way to concentrate on illusions like silent image while casting other spells without being a gnome? The +1rd/2 wizard levels just doesn't cut it for a low level elven illusionist. I'm trying to decide if it's worth losing the +2 int and +2 dex bonus for the ability to cast while maintaining my tricks!

Bards can spend Bardic Performance rounds to maintain concentration with the Spellsong feat.
