That'd be interesting - although I'm not sure if those cells produce that much power. https://www.sparkfun.com/products/9541 seems to imply it's less than 0.05mA per cell at 0.3v.
I think ideally the easiest thing would be if you could get enough of them in there that in series you could make the voltage up to ~4v, then you could connect it straight to the battery. Input power is small enough that overcharging is unlikely to be a problem.
I'm afraid that right now there are no 3d models of the case or inner frame available. Someone was going to look into it for the case but that never happened - however actually making your own model for the frame should be pretty easy.
