Digging the concept!!
I have a Honda Dominator (NX650) in Oz and am amazed at the effort that some tuners have exercised over these bikes to make them unrecognisable from their former lives. For example:

Google "NX650 Flat Tracker" and you will get loads of ideas along the lines of what you are thinking.
There was a build on Advrider, unfortunately, I can't access that site from work to give you the link
