Even without NRHO, LEO return is probably not possible unless your aerobreaking your lunar lander. It's 9km/s for LEO to Earth return and that doesn't include the ~3km/s LEO insertion burn. If you're whole hog on Starship then do reentry as well and skip Crew Dragon. The 86° frozen orbits are very curious, but whether you would want to do month-year long storage of non-starship landers in that orbit isn't clear to me.
