Congrats on picking the four star as your next "kit bash". A number of folks have done mods very similar to what you're planning. Take a look at what Mr70ss did with his Four Star.

Mr70ss was also kind enough to email me copies of his build process pictures.

Good luck with your kit and don't forget to snap some picts during the build. I know I can't wait to get started on mine - it should arrive at my LHS this weekend!
