Angelo: As long as her genetic modifications don't make her extra human, it's fine. As we stand, science has been very successful in cloning and manipulating small animals, so it's with in reason to say (if we ever get over the moral situation of it) that human cloning is technology within a decade or so. Also, it may be hard to find replacement pieces for your rail gun should it malfunction or break, and assuming it is pneumatically powered, compressed gasses would also be hard to come by. But it's fine. And bravo on your weaknesses! creative and realistic. PS. she looks like a female version of a Scout.
