Ned Steinberger tried this a few decades ago. I think during his trial and error period he discovered a couple of things about that design.
It's gonna be VERY headstock heavy.
Sustain is limited because of the lack of weight and mass.
Electronics (pickups, knobs, wires, etc) have to be as small as possible. This greatly limits tone options.
Ned solved the mass and sustain problem by using a thick epoxy/graphite kind of substance. I forget what it was called. He then had to add a little more size to the body just to accommodate electronics.
He solved the head heavy problem by putting the tuning pegs after the bridge. The opposite where you have them now
So basically, and I admire your attempt here, but you're building a Steinberger.
