Yes, I realize that I would use less gas if the engine was not running at all, but without pulling the stock drive train or adding a 5th wheel or doing some funky set up with bolt on wheel motors, it seems like there is no good way to do an ad on hybrid drive train, also Honda Civic's are common enough that if this does work then there are a ton of people who could copy it.

This may be more complicated than you want to go, but you could find the rear end from a CRV, and do a through-the road hybrid. (Granted, mounting this stuff in the back of Civic might make you want to just buy a or swap a CRV.) This would have the advantage that you could drive with the engine off at low speeds.
If your goal is mainly to displace driving energy from gas to electric, using the car as a plug-in hybrid, then efficiency is less of an issue. The bigger the battery pack the more displacement.
If you are thinking more along the lines of home-brewed IMA, then to gain overall efficiency, you need to make the engine smaller, so it is operating at best bsfc more of the time.
Interesting, I'll have to think a bit.
