I don't think so. I've looked at so-called theme generators and lately they've been looking quite stale. The other day I was looking for pro-bono (tax deduction) work to help a conservative news organization move from being just a blog and into a magazine-style theme, and I couldn't find one among hundreds I checked that had a good enough theme. It made me realize that there will always be room for custom theme development. Good thing I'm in that kind of business.
