There are some big problems with this anyway:
One, it would just be a guitar shaped guitar synth. A mere glorified keytar. You wouldn't be able to bend notes (though you could probably rig up a whammy bar), you wouldn't be able to do proper tapping, slap bass would be out, and it wouldn't sound as good as a normal guitar/bass anyway, because guitar synths just don't. The strings actually generate the sound.
The only crazy high-tech innovation I can think of wanting for a guitar, which I'm sure has been done or at least attempted, is to replace all the machine-heads with a motor/gear assembly so I could change tunings at the touch of a button. I'd also maybe want to build a multi-effects pedal and drum machine into the guitar. And some scrolling LCD displays. And make it look ridiculous.
Here's my conception of a laser guitar: Everytime I hit a big fat B flat power chord, a laser beam capable of cutting diamonds is emitted from the neck, killing anything in front of me.
When the cops came for me, I'd go down full of bullets, playing War Pigs.
