Looks pretty neat, but I think it might be kind of out of place in the Fallout world.
Everything each gang/faction uses, structure-wise, seem to be fixed up buildings from the old world.
I'm not sure if fanatical cultists would have the know-how or capability to construct a structure like this in the post-everythingblowntocrap world.
Even that neat little statue that the NCR erected in the ... outpost.. I forget the name, all the way as far southwest as you can go. It's built by an organized faction but it still looks like a pile of garbage glued together.
Would be great in Oblivion though.
I'm only speaking for the canon, of course. It's your mod, so you can do whatever you like.
