Since I fly a high-wing airplane, however, I would prefer that people
not descend upon me while I'm in the pattern. As an alternative to the
45, I would choose a mid-field crossover to the downwind, but not if
there's a NORDO aircraft in the pattern. He's expecting traffic to
enter from his right, not his left.

He should be expecting traffic to enter any time from anywhere, just
as you, and every competent pilot, are.
