SRX

I am working on juniper SRX configuration where i need to configure multicast static join on an external facing interface and then chnage the group ip address to our internal range and forward that to internally

Below is the config, 
is that something that is possible?

set protocols igmp interface ge-0/0/4.0 static group 239.8.8.8
set security nat static rule-set rs1 from zone EXTERNAL
set security nat static rule-set rs1 rule r1 match destination-address 239.8.8.8
set security nat static rule-set rs1 rule r1 then static-nat prefix 239.18.18.18/32


firewall policy

set security policies from-zone EXTERNAL to-zone INSIDE policy ALL match source-address any
set security policies from-zone EXTERNAL to-zone INSIDE policy ALL match destination-address any
set security policies from-zone EXTERNAL to-zone INSIDE policy ALL match application any
set security policies from-zone EXTERNAL to-zone INSIDE policy ALL then permit


pim joins
admin@SRX1500> show pim join

I am trying to setup similar scenario that Cisco has (Multicast Reflection service)
