The RS2 uses a 304mm disc so custom discs are needed

Yes - I'm doing this to my S2 which has G60 brakes

Not sure about the 5k so I'll leave that to someone who does

Biggest problem you may have in the USA is that the part number was
unique to the RS2 which was never sold there. These brackets are also
extremely expensive. Retail price is 150 GBP each which is approx 225
US$

I've got two of these brackets ready to fit. Measurements and part
number could be made available to anyone who asks.
