Replace HP QinQ with Juniper EX4300 Q-in-Q

I have a HP Switch that currently have 7 SVLANS on it. Each SVLAN is mapped to a physical port(Customer). Some SVLANS are mapped to multiple physical ports. 

I am trying to replace the HP Switch with a Juniper EX4300 Virtual Chassis(14.1x53-D40.8). I would like to recieve all of the SVLANS on a Fiber port as the HP does but create a trunk carrying all of the SVLANS(or Customer VLANS) to a single device. This way I don't have 7 different connections. 

I've looked over some Juniper Documentation but is not very clear. Any help would be appreciated.
