You can try doing a simple circuit-cross-connect since there are only
two local ports involved.  I /think/ QinQ should transparently pass
through this--just make sure your MTU is large enough.  You can also
have other units on these same interfaces doing routing or CCC as
well.  I last used this on M-series ca. 8.5, so YMMV on MX80 and more
modern code.

interfaces {
    xe-0/0/1 {
        description A;
	mtu 1600;
        vlan-tagging;
        encapsulation flexible-ethernet-services;
        unit 200 {
            encapsulation vlan-ccc;
            vlan-id 200;
	    family ccc;
        }
    }
    xe-0/0/2 {
        description B;
	mtu 1600;
        vlan-tagging;
        encapsulation flexible-ethernet-services;
        unit 200 {
            encapsulation vlan-ccc;
            vlan-id 200;
	    family ccc;
        }
    }
}
protocols {
    connections {
        interface-switch A-CCC-B {
            interface xe-0/0/1.200;
            interface xe-0/0/2.200;
        }
    }
    mpls {
        interface all;
        interface fxp0.0 {
            disable;
        }
    }
}
