Are you aware of TeeAction: https://dnsdist.org/reference/actions.html#TeeAction ? It can be used to duplicate UDP queries to a different IP:port than the selected backend, and since it does not stop the processing of subsequent rules, it can be used multiple times to duplicate the traffic to several hosts.
