Which leaves me with these few questions
1) Does a standard R200 diff (say ATS carbon or even a HLSD) swap into the Q45 diff housing?? Its obvious the pinion shaft bearings are actually bigger/longer/etc in the Q45 vs the standard R200 (Z32, 240sx, J30) diff.
2) Can a standard R200 diff (again, say S15 HLSD or ATS carbon) swap into a 350Z R200?? I suspect the answer is yes as a direct swap??

You sound like a Miata owner. I have a mystery diff in mine and at 80mph im about 4K rpm and the car creeps up in temp running like this for a while. I will be going 350z diff and axles mainly because the axles are stronger and more readily available. I rarely drive on the highway, around town the short gear ratio is super fun
