I wonder, for us losers with zero photoshop skillz, if it might be possible to automate the theming a bit through a web form. Check Ownskin.com (which allows theming for alot of cellphones) for an idea of what I'm talking about. I'd bet that most users might just want limited theming abilities, such as background and maybe ui-button colors. Any chance this could be done through a web-based app, rather than having to go through a whole Photoshop image?
