I dont think you will find many parts available. This is a fairly rare watch and not as mainstream as Rolex, Breitling, Etc.
Besides that - i dont think many gen parts would fit. Pretty much every rep lange is significantly different from the gen and that even includes case size so even a dial might not be able to fit properly in the rep case, let alone hands or anything else for that matter.
But still best of luck and keep us posted if you do manage to create something great.
