2 * 4040 * 4368 * 72 Hz * 20-bit / 1000^3 = 50.8225536 Gbps
In theory, yes, but that's assuming the monitor accepts higher refresh rates and doesn't skip frames, and you'd be losing color resolution. You would need to add 3840x4320 @ 72 Hz to each monitor with the totals set to 4040x4368.

Does Radeon Settings let you set YCbCr 4:2:2? You should be able to test 10 bpc with YCbCr 4:2:2 at 60 Hz without changing anything with CRU. If it won't let you do that, then CRU won't help.

Radeon VII should be able to read the extension blocks. Run this for me and post the log file:
