Would a Pure Energy 90ci/4500psi HPA tank fit in the pouch of a BT Bandolier 4+1 Harness?

I have a remote line and a BT Harness. I want to upgrade to HPA from my 20oz CO2, but don't want to chunk my harness. Thus I ask. I say 90ci because my local field's refill is a good hike away, and I like to go one game after another, without too much delay. For the record, I like Pure Energy, but if you can recomend a tank of 70ci or higher for the same price or less ($160) AND it's smaller in physical size, please let me know.
