What I doubt is the volume will be high enough to be worth the bother. If the battery needs rebuilding, they'll send it out to a third party like they do with starter motors or clutch linings. They'll continue to do alignments, tires, coolant changes, bearing swaps, etc. It's just the total pie is going to shrink and many places will need to close.
