Question on Six Moon Designs Fusion 65

I know some folks have received their new SMD Fusion 65s…so I was hoping you could help me visualize…

Has anyone put a BV500 inside? If yes, how much room is *really* left in the main compartment when the canister is in there? Would there be room for a WM sleeping bag, AND a big tarp + nest, AND some warm layers, AND a few other things? Or would a sleeping bag and bear barrel take up the whole main compartment?

Same questions, but for a Bearikade Expedition…
