You should have PTR records pointing to foo-e0 and foo-e1. Don't bother
with PTR records pointing to foo.

There shouldn't be any serious problems, but I recommend against it. It
will be unpredictable which name will show up when you do a reverse lookup.
If you look up 10.10.232.11, sometimes you'll get foo (and you won't know
which foo it's referring to) and other times you'll get foo-e0.
