I would use the D7200 with the 127mm f5 (635mm), which would make it 1.5x635=~950mm mounted on an APS Nikon camera (D7200). This should fill the frame with the moon -
check this before hand and if you are lucky give you the ISS-over-the-moon-shot that you said you were after with plenty of room to crop/zoom. Considerations:
1. Do you have lunar tracking on your mount? If so, set that and wait for ISS or try HD video (unfortunately much lower resolution, but much higher frame rate 30 or 60 fps on the D7200)
2. Check the buffer depth on the camera for how long you can shoot before full and also use a fast card.
3. Exposure - It may be diffcicult to get much detail on the ISS as it will likely be underexposed relative to the moon
4. Timing - very tight see Video at 0:30sec......
Best
