Stacked VDOM and Hardware Acceleration

Dear All,
I would like to migrate to a stacked vdom with the root learning a BGP default and relaying this to around 10 sub-vdoms via an inter-vdom link with an iBGP peering across the inter-link. I need to get around 10-15 Gbits though the platform as a whole with Jumbo frame support and I'm running the v6.0.3 train.
 
Having prep'ed the config, then I read that my 1500D platform would not be hardware accelerating any more than 2x links
 
As an alternative, I believe I can patch fibres between some of the physical ports and land these into different vdoms using 1.q subinterfaces. For resilience and improved speed, I would also like to make this a LAG.
 
Could anyone tell me please:
1. Is this approach of trunking multiple vlans across a physical cable for the physical inter-vdom link viable?
2. Is LACP possible between the vdom and are there any concerns like mac address or system id?
3. I use FGSP (and have a longer AS_PATH via the standby unit), is this compatible?
 
Thanks in advance for any advice.
 
Regards
 
James.

    yes that is doable , If I'm following you

    2. Is LACP possible between the vdom and are there any concerns like mac address or system id?
     
    What are we talking about here? Do you have a topology map?

    3. I use FGSP (and have a longer AS_PATH via the standby unit), is this compatible?
      what do you mean by standby,  AS_PATH and and FGSP has no bearing, explain what your talking about ?

    I have attached a diagram showing the intended setup. Basically traffic would enter from the North side (port 33 & port 34), then hop to a protected vdom via a LAG (ports 35 -> port 36 & port 37 -> port 38) before exiting on the South side, which again uses port 33 & port 34. 
     
    According to the 1500D fastpath diagram, I think this means that potentially both NP6 asics could be involved in a typical North-South flow (e.g. Packet enters on p33, across the LAG on p37->p38 then exit on p33 again). Would this be a problem given my requirement for around 10-15Gbits throughput?
     
    Thanks again for your help.
