yes, the oddworldian war that finally breaks would be great, but i think it's too soon, that kind of thing would be awesome for the oddworld finale. You know like the final game, where all the quintology heroes and their buds team up and thwart the industrialists once and for all and return oddworld to it's natural, peaceful state,
OR.... Abe could step in and say something and stop the war and everyone could live in peace (i find that being a better ending).
Those marching sligs could be the starters of a small but effective revolution, they could be marching and destroying something the mudokons hold dear, and when they see that it's destroyed, they get plum mad. Thus the war starts.
Just some of my thoughts
