While it's not quite clear to me either why you'd need two identical
gentoo repos (and if they're not identical, why is the non-gentoo-
official mirror still using the gentoo name?) or exactly what this config-
line does, the aliases= attribute, along with force=aliases, in
repos.conf, may be what you're looking for.
See the portage (5) manpage, repos.conf section, attributes supported in
sections of repositories subsection, under aliases and force.
Unfortunately, the description for aliases is anything but clear, tho the
usage (including comment) further down in the example subsection does
help some.
If that doesn't help, then while the portage devs may have some other
suggestions, the workaround that occurs to me is to use rsync's exclude/
filter options, so rsync ignores that file and doesn't sync it. I do[1]
that with a few custom files/dirs that I don't want synced, and rsync
ignores them just as I told it to. =:^)
See the rsync (1) manpage, --exclude, --exclude-from, --include, --
include-from and --filter=RULE options, as well as the filter rules,
include/exclude pattern rules, and anchoring include/exclude patterns
sections. However, be prepared to spend a bit of time studying, as these
options are very powerful/flexible/configurable and thus take some time
to figure out.
Once you have rsync ignoring the repo_name file, you can rename it as you
like.
However, do be aware that (as the repos.conf force option docs mention)
messing with this is very likely to invalidate the pre-generated metadata
cache, and if you don't regenerate it (egencache), portage will take a
*VERY* long time figuring stuff out, *MUCH* longer than usual, as it
won't have the benefit of the metadata cache for that repo.
Which again has me asking why you need two separate gentoo repos. Either
they're identical and the one should suffice, or the unofficial one
should be named something other than gentoo. In fact, at least in
theory, in addition to all the headaches not using a different name is
forcing on users, that's potentially trademark violation if it's publicly
available, different from the official gentoo mirror, and yet still
calling itself gentoo.

[1] rsync exclude options: I actually use gentoo's git-based usersync repo
on github, now, and thus don't rsync any repos all any more, here, and
git of course has its git-ignore feature/files, which I use now. But I
used rsync's exclude as suggested above, for years. Worked fine. =:^)
