hmm I think it might look odd trying to unwrap it onto a flat image just so it can be wrapped back onto a chuck..not to mention that the protrusions that make the saber handle what it is would look a little off...
Honestly what I would do probably is possibly get a plain silver chuck..and then get the extra parts and the knock off replica parts from somewhere like thecustomsabershop (look in the graflex/heiland section (since it's a heiland modified flash) and the grips section) and fit them over the chuck itself to retain the look and feel with the body protrusions...but I'm sure I'm making it more complicated than need be..
