I happen to have a fiberglass 6ft A-frame in my garage. I imagine I could tow it out on a $10 inflatable raft. I'd just need to fabricate a base to give it a bigger footprint in the mud below. And yes, that would confuse the hell out of the locals in the Jon boats.
The gears in my head are spinning right now on a modular outrigger system I could easily paddle with, but could be deployed and stowed while out on the water. As much as I'd like to avoid a gaudy looking PVC frame with lobster floats, it's hard to argue with the ease of working with the materials and their low costs.
