Here is the VW tdi as an industrial engine.

Given the application I would expect there is a big honkin flywheel on
this thing that would be removed for aviation purposes. Then after
replacing the the alternator etc etc. It would still be heavy, but
potentially doable.

I would wonder about the potentially doable part. It is nearly 300 lbs, and
only 78 HP. Even if you could get 100 lbs off of it, (doubtful) that would
still be 200 lbs, for less than 80 HP. That is bad in anybody's book.
