Multicast is a destination address. If you want to change, at least the HA pair should be pointing to the same destination.
224.0.0.245 does not look to be a registered, and I guess is just because 245 is a conversation of F5 from hex to decimal (like they do with the default management IP). Here are some reserved IPs:

I guess that the receiving devices will differentiate based in the source IP or source MAC, when they receive a packet from the peer device. You can take a tcpdump, use the wireshark plugin (as I think it has HA decoders), and check what happens.

I personally, never configure multicast. An HA vlan and management as unicast, should be more then enough. However, F5 does recommend that per this documentation:
