RT 4.2.1 and new cameras

Well, I had a feeling. Just didn’t know if there was a way to get closer or develop my own profile?

I have an older version of the Adobe Creative Suite that I would like to keep using for the time being, so I am stuck at 10.8. I use Capture One for all of my raw conversions and it is a newer version than Adobe CS, but the latest cameras are not supported there either.
