It can be done, there is an electric super charger out there that does work. Its a screw type compressor with what looks like 3 starter motors powering it. That thing had like a 10% or 20% duty cycle if your electrical could keep up.
I would just go with a clutched setup.

It seems like the clutch would have to go on the S/C pulley so the belt would always be sapping power.
What I'm really trying to do is boost the idle to 1500rpm flat spot that my 4.0 Jeep has, I don't care if it runs out of puff at 2000rpm since I very rarely rev it that high. It seems like an electric S/C would be far more suited to the task than a mechanical setup. If it saves me a downshift on the highway or even means I don't have to regear my axles when I add bigger tyres it would be a huge win.
Yes a S/C can easily consume 20hp to run, but that's at redline where us Ecomodders rarely venture.
