I do not think it is valid to have several CNAMEs. I may be
wrong, but I've never seen it tried.

The classical way is to have

relay00.dev.domain.net  IN A    10.0.0.1
relay01.dev.domain.net  IN A    10.0.0.2
relay.dev.domain.net    IN A    10.0.0.1
relay.dev.domain.net    IN A    10.0.0.2

(and the corresponding
1.0.0.10.in-addr.arpa   IN PTR  relay00.dev.domain.net.
2.0.0.10.in-addr.arpa   IN PTR  relay01.dev.domain.net.
)

You will not have any problems with that.
