No .. It's perfectly balanced ... just center of 17kw 2012 IMA motor doesn't lined up with the center of the ICE output .. even though the case mounting bolts line up fine.

If you don't use the FAS injector kill switch ... just use MIMA or IMA-C&C to drive the ICE to fast enough RPMs that it goes into fuel cut on it's own .. you don't get any cell or error codes .. at least I never have .. it has only been the injector kill switch (for lower RPM use) that I ever got cell/error codes triggered.
Yes ... It isn't much power at all .. especially with the ICE parasitic losses .. I've only done it in low power states at lower RPMs .. parking lots , stop and go-ish traffic .. or low enough power that 5th LB is under 60% ICE Load.
On a flat (or very close to it) I can maintain a bit over 45 MPH in 5th for as long as my battery has power to give .. small hills are an entirely different story ... Maybe I'll do some runs to put firmer real world numbers on the face of it .. but my current setup still has all those ICE parasitic losses .. and I'm not running any of Peter's more power mods ... just a tiny bit of more power from the A123 pack being a nominal 156v instead of 144 .. ~8% more v and thus also ~8% more A .. or about ~16% more power .. and less internal resistance (thus less voltage sag) ... depending on pack temperature about ~40% less IMA pack internal resistance.

You'd keep auto-stop intact, and could have as much or as little power as you'd like. You could even use both motors at once when accelerating if you so desired.
^ I was thinking about this some weeks ago, and at that point, I decided, why even keep the gas engine? If you're going to add a new battery and electric motor, you can save yourself ~350lbs by removing the ICE and throwing some extra battery in there.

I guess .. it's just a mater of personal preference and how much one wants to do .. what final result one is looking for.
BEV conversion is 100% perfectly doable.
