Yeah , you can do so....You don't need any explicit configuration on SRX
Side, while you would need to enable LACP on Switch port level.

All the 6 interfaces/Firewall will participate in one reth interface and
then you can enable vlan-tagging to provision inter-vlan routing. You will
be having interface like (e.g) reth1.100, reth1.110, reth1.120 as per your
VLANs configuration.
