The camel hump idea is asolutely awesome. If you could sketch what you are contemplating... pics = 1000 words … I have an idea of what you are talking about...just not quite sure. Maybe incorporate wing hold down using nylon screws/plywood? No BBQ skewers?
The pod mounted nose landing gear sounds definitely viable, would have to then definitely consider stopping the "foamboard" nose at the nose gear line and design a box/plate to house the nose gear pod. Because the nose is not square sided it will require some...fiddling.
