Passing VLAN tags on physical interface that has sub-interfaces

I have the following interface configuration on an EX4550:

   ae0 {
        description Test;
        vlan-tagging;
        aggregated-ether-options {
            lacp {
                active;
                periodic fast;
            }
        }
        unit 2007 {
            vlan-id 2007;
            family inet {
                address 1.1.1.1/30
                }
             family mpls {
               }
            }
        }
    }  

I have a need to pass additional tagged VLANs on ae0 as well.  Is this possible?

I realize this is typically a use-case for "flexible-ethernet-services," but this feature is not available on the EX4550 platform.

I typically use RVI's (and thus "family ethernet-switching") for routed VLAN interfaces, but I need this interface to participate in LDP/MPLS, so I'm forced to use this style of configuration since "family mpls" can not be applied on a) RVI L3 interfaces or b) interfaces that also have "family ethernet-switching".

Thanks for any advice.
