No question if you optimize for cruise cooling for minimum drag, you will undoubtedly encounter a cooling deficit at high power/low airspeeds. But, pulling back on power (and keeping airflow high as high as practical) should allow it to work.
Monty, you could also see if you can work in the same type of system that I'm planning. Follow my logic for a moment.
When do you need that extra bit of cooling? ...on really hot days at low altituded.
When do you wish most that you had airconditioning in the plane? ...on really hot days at low altitude!
Since you also plan to move your radiators back into the wing, see if you can rig up a "heat exchanger with a box on top" in line with your cabin air intake. On really hot days, dump it full of ice before takeoff. You get to stay a little cooler under the solar collector. As the ice melts, you have to get rid of the drippings. Just run a drip tube to an exit that's in front of the radiators. Presto! Two birds, one stone.
This is easy on the Delta. Big fat strakes in front of you that are basically empty space. I have no idea how it would fit in your project.

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
