Broadcast is still a single packet. Unless your L2 network is
malfunctioning, everyone on the network will only see one copy of the
frame.

IMO your goal is not best solved here. Ethernet specifically isn't
suited for this. I would let the higher layers (application) do the
duplication/deduplication, maybe using two different TCP sessions with
different source and destionation addresses which could be engineered to
take different paths.
