A friend of mine who is also one-legged and a flyfisher uses one of the original Pungos as her platform. She doesn't use a second leg at all so storing it isn't the issue for her but you could very very easily stow one under the front deck of the Pungo. Use a carabiner and attach it to a deck bungee. Be VERY careful about tying things onto the kayak with lines that hang loose. If you actually do capsize, it's too easy to get tangled in dangling lines. I'm a big girl with lousy balance and I found the Pungo was rock solid stable as a casting platform. Mine was rotomolded 14 ft... too long and too heavy probably for what you want. Jed's suggestion looks like a good one.
