I love the Hasbro as a nostalgic Toy, I think the way the the stock works (original 1970's style) is great too.
However I think if you go to the trouble of putting a suit together, no mater how you dress up the Hasbro its never going to look that brill so I think you should kinda stride to improve your blaster, and even if you don't make one the, something like the SDS version looks pretty sweet.
