WOW WOW WOW...
I say go for it. Or, get some wood and test it. Not for sound of course but how it feels. Then, if it's acceptable shoot the body with light coats. Now there are paints available that have very similar look, but would go on much thinner. Just a thought.
As for tone, well there is something to be said for the effect woods have in the overall tone. I'm sure it's no surprise to you.
Who's to say it won't sound good? Will it, won't it? Guitars made of all sorts of things sound good to someone. Is the way it sounds everything, or is the satisfaction of doing something different just to look at worth more to you?
There are guitars with the pickups isolated from the the body completely so as not to introduce any "body" coloration. Is this wrong? Does it sound "bad"? Likely it sounds different. Is different a bad thing...?
