  I would expect it to work.  Never tried it, and dunno if it'd be
common practice, but lo0 is largely just an interface, and just as
have 2 customers come in across a tagged Gig trunk to be dumped into
separate VRFs should work, so too should the same IP in diff logical
units on lo0.  Only 1 way to find out for sure though! (commit check)
