I think this question is irrelevant because you've placed so many unrealistic fixed constraints on your example. You say "camera specs such as QE, noise etc are held constant" yet you say both systems have 1"/pixel at different focal lengths.

Realistically your pixel size will have changed in order to have 1"/pixel at both focal lengths, affecting QE and probably other aspects of the camera (full well depth?), noise characteristics of the camera?, etc.
