This would work in at least KOMA-Script.

Check org-match-substring-regexp.  As you see at subscripts must start
with something that's not a space.  So I guess you could use a filter to
remove some otherwise unused character or the the like...  Or change the
the syntax table changed so that zero width space is somehow not an \s,
but that's probably asking for trouble.
