Possible but there are times where the elk get balled up on the private and you are waiting for them to leave. When leave you have to hurry and catch them as they cross public because they typically won’t stay long on the public without getting pushed back into some private. I agree that some general units are better.
The only real advantage to 25/27 is if you are able to hunt the season is really long. As a local it is hard to beat just because you have such a long window to catch the elk on the public.
