It'll work.

However, installing Gentoo is a huge PITA, being almost the same
as installing LFS.

I do not strictly use Gentoo, but only their automated build
system known as Portage.

My strategy has always been to clone my existing installations
onto a new machine.  Ideally, this would involve cross compiling
which is another PITA.  But if the new CPU ranks above the old
CPU then a straightforward copy will allow the new machine to
boot with the old software packages.

In my current case, however, I assumed that the Xeon W-2223
would be identical, except for AVX-512, with the Xeon W-1270P.
However, it is not and the new machine would not boot using
software compiled on the Xeon W-2223.

I had to fall back to the Core i7 machine to build the software
and in this way the new Xeon W-1270P now boots.  The Core i7 is
"below" the Xeon W-1270P.

The next step is to use Gentoo Portage to rebuild everything
(i.e. the "world") according to the Xeon W-1270P specs.

My approach is totally unconventional but it works magnificently.
I eschew both systemd and SysV for booting and use my own boot
scripts (derived from LFS).  Gentoo Portage is used only for
automated building.  Otherwise my systems are not Gentoo.

I should post my unique GNU/Linux "distro" to GitLab, but
most users are lackeys and would never take notice.

Yes, my systems are different from any other GNU/Linux
"distro."  I should perhaps create "Farley's Fantastic Linux"
but, as I already indicated, the lackeys would never notice.
