If I do get around to trying this, I'll probably do it to my telecaster bitzer, so there should be fewer sticky-outy bits to worry about, and the join could possibly around the outline of the back.
There's a rig rundown of ZZ Top when Elwood was the guitar & bass tech, and he showed Billy & Dusty's 'Peelers' which look like they were left in a barn, but they're actually a custom bolin tele & precision with a custom printed vinyl wrap.
