The combustion side would need dowels. The top RPM would be limited by crank
flex. For a 12A crank flex is a problem above 10,000 RPM. For a 13B above
9,500 RPM. For this thing maybe 7,000 RPM.

Two ceramic seals. Two springs each.

Two Pports each set of housings. Modest port timing. Looking for torque and
a 2:1 reduction for cruise at below 5,000 RPM.

Dry sumped.

About $100,000.00 short at the moment but if the market goes back up???.

Could you use two rotor housings, brazed then pinned on the compression
side?  Then they wouldn't really need to be special either, and you'd
get FOUR plugs per cylinder.

Side seals would be standard, but would the apex seals have to be
special made...or could you use two of those side-by-side?

You would have to have either a monster bridge port or a peripheral port
to feed the monster.

Renesis rotor housings probably wouldn't work.  The side exhaust would
be to restrictive for twice the volume.

You'd need to build a new oil pan, or use a remote sump.  Simple.
Special made compression bolts are also a cinch.

On a guess, you'd be adding about 15lbs per rotor (?).   It could
possibly end up being a 400Hp engine with an installed weight under
350lbs(?).
