Even for smaller pilots, current cockpits are usually too snug.

I'm normal build and 5'10" so I have no trouble fitting in my Ventus 2cM, and its comfortable, but I can't move much and little stowage space. I always have more 'stuff' than places to stow it where I can reach it. There is space behind the backrest, but I can't reach things there. Things stuffed down the cockpit sides tend to become invisible and unreachable in flight especially since arm movement is very restricted. The side pockets are narrow and already filled. I typically fly with 'stuff' lying on my chest (headset, map, sunglasses, cellphone, peebag, checklists, snacks).

Another comment: I once developed cramp in flight. It was extremely painful since I could not move in a way to relieve it.

You could always get a cabin class glider like the Waco CG-4A. It could even be customized with a bathroom in back and a small galley for snacks. And maybe a dirt bike in case you have to land out in the boonies. Better tell the Pawnee pilot you want at least 70 on tow though.
