I think that all you have to do to make your "Lycoming" into a "pittss1c
Super Advanced Powerplant" is to remove the dataplate from the engine
and attach one made by you. It is now uncertified and you would be free
to do what you want with it.

I was just thinking, the designer sets the operating limitations of a
homebuilt's engine.
therefore one could define an engine based on lycoming parts (up to 100%
lycoming) to have a max continous RPM of...say 2000. (as part of "your"
design to get a higher TBO)

If I was to build up an engine with parts out of my garage, I would set
the operating limitations, and would set the Vne of my own design/airplane.
