If all they are doing is allowing color changes and slight UI tweaks (and the undo button), why not take a page from online gaming's playbook and just sell cosmetics?
There is pretty much no limit to what could be sold as a cosmetic...add "flair" to the twitter bird (googly eyes, hats, etc) ($5.99 - $25.99)...make circle logo on your profile an octagon ($1.99), a triangle ($1.25)...with a blue border for an extra $.99....etc

I bet they'd make gobs more than a $2.99/mo.
