I like the minifig. The combination is an obvious idea. Thats the way the minifig should have looked right from the start.
As for the blaster... this one spoils the impressiona bit. The unique form of Fetts weapon is not properly mirrored by any original LEGO part, but there are serveral options provided by e.g. Little Armory Toys or The Little Arms Shop. Also ebay might be worth a look.
If you want to have an impression, look here, I have rebuilt on digitally. Its from Little Armory Toyshttp://www.brickshelf.com/cgi-bin/gallery.cgi?i=1722043
