1) I once cleared the Wall on AoB with Inv. globe. It was rather easy - knights get close to me and got killed by themselves and the rest were killed by my chainsaw, but way out wasn't possible. It's possible to make them attack the Wall and kill it by standing near it (I tried with cheating - really possible) but it would kill you many times. You need full backpack of large meds to survive THAT.
2)Not knowing what to do with that wall I onceteleported there with double shotgun. Cleared it easily. On AoMr I also tried to clean it. I did. But the idea of implementing barrels would be nice because I've got stuck there once with 1 phase device.(I was savescumming to try to go there).
So, the idea is nice, but Phasers do it. The prblem is like the Roc.Lan. - it doesn't spawn!
