This will obviously only work for UDP (not TCP, because of the sequence & acknowledgement numbers), so you might find it easiest to set up a DNAT rule to a multicast address, and then use a multicasting router to send the packets to their required destinations? I certainly can't think of a way netfilter can make two packets out of one - its basic job, after all, is to turn one packet into none at all in some circumstances (the DROP target)....
