Well, definitely Raptor Vac is capable of operating at sea level. That's the part that's really complicating its design, pushing achievable chamber pressure high enough to avoid flow separation and strengthening the nozzle.

There are some practical size constraints too. Can’t be too big to fit in the engine compartment. But, it could be a little bigger. 380 sec Isp would be nice.
