theres no limit to the diferent battle scenes you could make! (well there is, but shadap) I seriusly think you shouldnt stop with bridges, if you can produce lots of high quality battlescenes then you will be allmost as epic as that magelord guy with the scripts!
I realy like the one where theres tents if your attacked whilst camping- give the player a terrain disadvantage and meybe make the enemy spawn on more than one side (if possible) to simulate the player being taken by surprise- perhapse doing the same if the player catches the enemy camping (i dont know if they do or not)
you could take it a step further and make battles near villages and towns into farmland battles! and a small chance in feild battles for there to be a couple of houses, or a hunting lodge or anything realy- just the kind of stuff you would expect to see in a medieval countryside. btw, on a similar topic: in the mod Talera (something of talera, cant remember, its a fantasy mod) the forests are realy dense- much more like real life forrests, is there any way you could do that for native M&B, because those forest fights were fantastic, realy brought in new tactics.
(sorry for all the ideas/requests, but your realy on to something with this)
