Hi ironraven,

I found another supplier of ALICE/Patern 64 products on the internet at Drop Zone Tactical of Edmonton, Alberta, http://www.dropzonetactical.com/backpacks/64alice.html

I see in this website photos how the ALICE frame is different from the Canadian 64 frame but it states that these new bags will attach to both.

It may not be as large as you are looking for.
