You know, you said that after that Ancient Device moved the Mandalorian System to the new location all that was left was a black hole. That's NOT how physics works, you need MASS to create black holes. You would just be leaving a more perfect vacuum behind after you remove the Systems. If anything you'd have more chance of creating a black hole or weird gravitational occurences at the place where the Mandalorian Systems appear.
Now that's a proper sci fi battle right there! I love it! Have you considered Power Armor along with Orbital Insertion Troopers? Something along the likes of ODSTs or maybe Space Marine Drop pods? It would fit the Mandalorians pretty well without being too out of lore. Maybe railguns and gauss guns or humanoid weapons platform or simply Mechas? It's not to late introduce new technology and tactics in this stagnat universe.
