To illustrate just the type of thing I would be happy to help with, here is an interpretation of the Rebel tower that was seen on Yavin in the movies. Its obviously not an exact replica, because I have no idea how you would get into it, short of a personalized lifting crane. I am not sure how exactly to extend it ingame (it'd have to be a vehicle), a middle ground would simply be the ladder reaching all the way up.

In short, its just a general scouting tower or sniper nest if you wish to call it that. Whether you already have something like this modelled for the mod doesnt matter for me as its just an example, it was the first and simplest little building I could think of, lol.
