if IMC REFL is not increasing, I don't think its a mis-alignment. Usually, REFL is a more sensitive indicator of alignment than TRANS since its usually near zero. Maybe the MC2 TRANS PD is not centered or doesn't have enough lens action.
to reduce the DC load on MC2, you could have a slow releif drive the ETMs and DC and minimize LSC-MCL
