This looks like a shortened duplication of a subset of multilib-portage
features. While this wont hurt multilib-portage (since it does exclude
most actions on ebuilds with USE=multilib), it will mean a rewrite for
many ebuilds, which then again need another rewrite (or more likely
revert), when multilib-portage is accepted in a future EAPI.

So i would prefer some help/support with multilib-portage to get it
accepted sooner, instead of this additional workaround for a subset of
packages.

P.S.: I know, that users, who want up-to-date 32bit drivers for games
and wine do use multilib-portage, so we already have a working solution
for this issue.
