A request to IANA would result in getting 7016 and 7017 so far as I can
tell.  (Or something else if you wanted something else, but those seem
like the most reasonable choices.)  You can generally ask IANA for the
port numbers that you want.

I think it would be better to register new port numbers unless there's a
substantial backward-compatibility benefit for existing installations to
reusing the current port numbers.  I don't have a good feel of the
combined current RxOSD and MR-AFS installation base, though.
