>>18952203I think you are just being too pessimistic about it.
Bottomline if GF really wanted to do R/S remakes this gen it could be done even if they resort to:
Just ditching contests
Not making pokemon tradeable back to XY
Make mons tradeable between XY and R/S but give a warning that all contest data for that poke will be erased
Some other programming wizardry that allows it, trust me if you think something can't be done 9 times out of 10 someone has already tried and done it.
