That's not quite what I meant.

There's very few recipes that we are willing to carry multiple versions
of in main layers, Xen is one of them. If it wasn't for that, this would be
a definite no, since if someone wants new features, we simply point
them at the next release.

It also isn't something that I'd continually do (again, I'm only talking
about the official meta-virt layers/branches) as more Xen releases
arrive through the lifetime of a LTS. The support matrix is too high
at that point, and again, I'd just point to the new releases.

It should definitely be possible, and something I'm willing to do as it is
an already tested version in master. I also so like to keep things we
want to support in meta-virt itself, versus external mixin layers
(when possible).

Have you tried just taking the recipes from meta-virt master and seeing
how the work on scarthgap ? I'm still doing current release bug fixing
and package updates, so it will be a while before I get a chance to try
that myself.
