Excellent work, looking forward to seeing more! It makes me want to make a diorama for my figure collection!
If you're still looking for the different weapons, you should know that the other variations of the figures come packed with other weapons. Buck comes with the MA5B, Dutch comes with the Spartan Laser, etc. I'm sure you can source these if you go to the McFarlane website or forums, theres usually someone trading in just weapons.
Also, I'm sure this will find a nice home in your diorama
