I think it would be a bit more than just making new OOBs there would have to be some code changes to & I cant see most people enjoying it.
This would mainly be static battles with sides sat in trenches & huge artillery presence hampering movement further should you try an assault. most kills would be scored by the arty & I am guessing MGs.
The AI would probably be cannon fodder if it assaulted & the human player would spend most of his time trying to rally troops if he tried it.
Sounds boring to me plot arty move a couple of units, rinse & repeat
