Ohio isn't that far from the Axiom plant. Maybe you could just feed your LFE channel over the internet up to Dwight and have them pump it out over the SWUT (SubWoofer Under Test) on the tower
You won't get full room gain but at worst you would get "ground gain" (sub is only radiating into a hemisphere rather than a sphere) and if you had a solid outside wall you could get at least half the output you would get in a room (eg -3db) which should make a pretty significant difference.
From a practical standpoint this should be do-able, and seems like it would be a pretty cool product. Downside is that ideally you would make it in some kind of inherently waterproof material (like the Algonquins) and that would have to be pretty thick/expensive for what is probably a pretty low volume product.
I guess this is another (wordy) vote for the moving dolly
