I've thought about this myself, the cost of the kits seem high although I haven't priced any of the exotic woods some of these fits are made from. Seems it would be a fairly simple project to undertake, if things come out good you could probably make your initial cost back by selling a few sets on the forum. Give us details as your idea progresses.
BTW I think I remember your wood grain paper covering, I thought it was a great bang for the buck project.

I hate to advocate weird chemicals, alcohol, violence or insanity to anyone... but they've always worked for me.
