Yes, but it's probably not a sensible thing to do. Why do want half
the reverse lookups of the 192.168.0.1 to return one name and the other
half return another name?

Well that could be because you're querying a name server which doesn't
do round-robin or has been configured to always return a set of
resource records in the same order. Or you're just unlucky because
every time you do a lookup, another odd-numbered set of lookups is
done before you lookup the name again.

Round robin works on ANY set of identical resource records of any

whatsoever to do with PTR records.
