Of course it's possible!
By the way, does "F2LL" stand for anything? Please don't start combining acronyms arbitrarily, or else I'll start getting back at you with EPF2LLEO and CPF2LLCO for ELS and CLS...
Also, I never really liked Petrus orientation. I still prefer to do the orientation with a different definition of good and bad, so that the 2x2x3 is held at DL or DR, and I can fix edges using R or L turns (and R U R' type moves).
So you want to restrict one of the free sides to 180 degree turns? I think it makes a lot of sense to define EO so that you can use the two sides freely.
