It looks to me like USE=vanilla controls only whether or not bundled timezone data is used. If that's the case (double-check!), it's probably safe to unmerge timezone-data and re-emerge glibc with USE=vanilla. To be safe, you can bundle up your existing glibc with quickpkg. Then if something goes wrong, you can always boot to a liveCD and unpack the old version.
