Is it possible to make a 4 rotor rotary engine by putting together 2  2-rotor s?

Yes.  I have seen people put together a 24 cylinder engine by bolting 3 V-8 crank to crank.  Fuel mixtures and volume can be some what of a problem.

Do you think rotary engines might have been a bit more popular with a different name?

Yes, the 4-rotor Mazda 787B won LeMans in 1991. Mazda offered a 3-rotor in the 1990-1995 Eunos Cosmo.

But would you believe *twelve*? This guy tied three banks of four rotors together to fit in the size of a V-8:

if your an engineer then no problem , if your not an engineer then you have no chance . and you do happen to know the fundementals on a single lobe to a twin lobe constuction and design . .

I think in the early days, someone did make an experimental 4 rotor:  NSU, Mazda or might have been Mercedes.  As I recall, it was mad powerful - - but as with a conventional engine, the frictional losses went up disproportionate to the power increase and it negated the value of compactness.  There are 1 rotors . . . a 2 rotor is proven and can be as powerful as needed.
