Latency from 2-3 feet of wire is not problematic. But depending on how much data you want to move that distance and how thick a bundle of wires you are willing to use, power to move all those bits could be an issue.
USB-C can do 40Gbps. That's more than enough for a bunch of screens and cameras.
40Gbps is not enough to run the screen for one eye at the resolution/framerate/HDR it's running at. You'd have to chop the bpc to 8 or the refresh rate to about 80hz. And then you'd still need another one for the other eye, and a third one for the cameras.
