Here's what I'm considering doing, and I want to know if it's possible, and how much it would cost (this is a semi-long-term goal):
RG-321MH (have on at a local shop, not sure of price, looks great though

)
And add these mods:
Piezo bridge
Synth access (through bridge?? or Roland GK-2A internal?)
Sustainiac
DiMarzio Super Distortion (bridge) and ???? (neck) (suggestions?)
Direct mounted pickups, no rings (possible?)
And if necessary a refinish depending if routing is needed/will effect finish at all, would be just a simple matte finish of some kind, black or grey or something.
Is this possible? Is it worth the time/money? And how much would it cost? And who should I get to do the work? Is it worth doing myself (with help from my dad who has more woodworking and wiring experience than me)?
Edit: Plan B
Or would it be a better idea/more worth it to do these mods (piezo, synth, sustainer) to my Squier Strat (which already has the DiMarzio Super Distortion and could use a new bridge/re-wiring anyways)?
I looked around and I'm thinking Graphtech Ghost saddles would be the best way to do this. Can you wire up both Midi and Piezo at once? I'm willing to sacrifice my tone knobs for this project, and just go:
volume
piezo volume
sustainer knob (can't remember proper name for this)
And then add mini-switches for the rest:
piezo on/off
MIDI on/off
Sustainer on/off
Sustainer mode
Btw, which Sustainiac pickup is the one that sounds like a single-coil when turned off?
