My dream engine is
still a 3-4 liter two rotor Wankel with a built-in prop bearing
and aircooled, designed to run at about 2800-3000 RPM.   No
danger of getting it, sadly.  HMMM??

Is there any real possibility of designing one of these here and
getting a prototype built?  Jeff has done a lot of this and could
guide us, plus there is a lot of design and engineering talent
out there.   Pipe dream or mere insanity?

Well, there are dreams and then there is engineering reality.
Here is my opinion:

It makes no sense to design a diesel engine for use at 9,000 rpm.
It makes no sense to design a wankel for high power use at
2800 rpm. The design of each, and all practical examples of each
to date, has characteristics which lead quite naturally to one being
a low rpm engine, and the other being a high rpm engine. Rotary
engines spin fast ... it is inherent in the design.
