QinQ configuration being provider and customer edge on same switch

Hi,

I'm configuringing my coreswitches 2x HP5800 in the datacenter of my customer.

On the coreswitches there will be connected some Servers, Firewall's and connections. One of the connections is from Equinix datacenter, called Cloud Exchange. Via this fiber connection, we are going to connect to Microsft Azure, via the Microsoft Express route.

To make this possible, Equinix requires QinQ, where I can define the S-VLAN myselfe, this one is passed trough to Microsoft. For each microsoft service (Private / Public / office365) I can than assign an C-VLAN.

The question is, how can I have for Example, VLAN 200 as C-VLAN on the 5800 (and also on microsoft side) and than add the S-TAG (for eg VLAN1000) before sending it to the fiber-uplink.

Normally the provider add's the S-VLAN when I send my tagged frames into their port, but know in this specific configuration, my core will be provider and customer switch. The only solution I can think of, is to create a port wich add's the S-TAG, and than use a patch cable from for example interface g1/0/1 to g1/0/20 where g1/0/1 is a trunk port with vlan 200 and and g1/0/20 is an QinQ port wich add's the S-TAG vlan 1000. The uplink port to Equinix is than tagged as vlan 1000.. 

Does someone know how to do this without using a physical cable?
