Multicast Routing GSM7352S

I would like to know if the following is possible and some direction on how to begin.

I have multiple video sources (multicast) that are attached to the GSM7352 on VLAN 2. I would like to route all the traffic to VLAN 3 on the same switch. I also have multiple switches (connected via 2 port LAG) where I would like the same multicast traffic to be available on VLAN 5. The switches that are connected via the LAG only have IGMP snooping.

Is it possble for a join request to go over the LAG on VLAN 5 then the GSM7352 will route the multicast address from VLAN 2 to VLAN 3?

I do not have a mulitcast router, unless I can use the same GSM7352 as one.

Thanks
