Reconsider: 2 frames at 60Hz was an intolerable 33ms too long, he needed it down to 16ms total. Your optimistic 1ms latency cuts into that maximum refresh time by 7%, time that will (or is already) in high demand by meaningful/viable applications.

You're also assuming a highly customized/optimized scenario for the wireless hop, nigh unto a straight analog signal. Digital processing will extend that, likely adding at least one full frame delay - again, something Carmack severely objected to and fought mightily against.
