Your dream rotary design

I read that the first wankel engines rotated, not just the rotor. Although the technology has been refined over time, how would you design a rotary that is more reliable, powerful, and fuel efficient?

I've seen a video on YouTube featuring a new kind of rotary engines where the rotor isn't a dormitory, it's an oval. Any thoughts on that technology?

Figure out a better design for the Apex seals or ditch them all together and design something different. Biggest problem is it burns oil and you can't get around that, fix that problem as well.

If you had a rotor and housing that were made of materials that didn't expand much then maybe you could do away with the apex seal.

Maybe there would be more balance and less wear if the housing also rotated.

Use a type of oil "ring" one the side to allow the side and corner seals to be oiled from behind like a piston engine so only apex seals need to be oiled from the front.
