I won't say such a thing does not exist, but continuous yumable rolling
rawhide would not be possible in this case, and my experience is you can
"forget" to go through anaconda most of the releases.

This could probably be solved by doing the package upgrade bit in
several passes

(Also please note several passes are only needed if some of those needed
bits must be done on a cold system - the rest is only normal package
install ordering yum does all the time, just make the packages that need
firstboot to be run depend on it)
