I was just thinking about this. I ran across some cheap bodies at guitarfetish.com. Look under their Factory Buyout and Clearance Sale tab. You can get a body and neck for about $60. I was thinking of experimenting with this as a platform to try some things out, like a sustainer. But then I started adding the price up in my head. A few hundred for the electronics, about a hunderd for a good tremolo, another couple hundred for all the "other parts" (tuners, nut, etc.).
But then I figured, I could be fighting the platform all along and not know if my iconcept was bad or the platform. And like said earlier, I'd have a guitar that was worth much less than the parts I put on it.
I think I might stick with Warmoth bodies and necks and I know the platfrom will be very good to start with.
