Sure, you could do this... or you could just delete the accessories... unless one of them is a belt-driven smog pump or something similar.

If you absolutely have to keep the A/C, you could drive that from a e-motor, but you could also just attach the e-motor to it, in place of the clutch assembly that's already on it.

You could then use the clutch assembly to freewheel the PS pump until the steering wheel moved more than a few degrees from center, where it would trigger a contact strip that would engage the A/C clutch driven PS pump.

I still +2 on just deleting the accessories, removing the starter, going with an e-motor and a toothed belt that will put out about 10HP for 30 seconds, and blocking the IACV on the engine.

This will mean that you use the e-motor to start moving from red lights, any time you come to a complete stop or clutch in for long enough, the engine stalls. That way, you don't have to worry about turning the key off, then back on, etc... you just leave the key on, the gasser stalls, the e-motor takes off for you when you press the button, and the gasser is driven by it, so it will start on it's own when the RPM's are high enough to allow the engine to run without external power. (right around 300 RPM, the engine will run, but won't create useable power until nearly 500-750 RPM, which is crawling in first gear.)

Imagine how much gas you won't be using when your engine doesn't run at red lights or any time you come to a complete stop, and the e-motor is doing all your <10MPH driving...
