Regenerating portraiture on everyone?

[Metalkatt]

Is there a way to mass-regen portraiture/thumbs on an entire hood?  The Island went foom because I'm an idiot, and the defaults I was using were jinxed.  I've restored from a backup, but many of the residents had default-style skins... now I have normal looking sims with fuzzy accessories, and I want to SimSurgery them where they should be.  It's kinda hard to do, though, when the thumbs are still fuzzies.

Mass makeovers?

The FFS Lot Debugger has an option to regenerate portraits, but it's on a sim-by-sim basis.  Also, just having them 'change appearance' in the mirror usually forces a new portrait.

No way to do it en-mass, though, that I'm aware of.
