I'm not really sure that there realistically could be any other type of battle damage done to one of these fragile a/c and still have it make a survivable landing........
Maybe some of the battle damage (machine gun bullet holes) could have damaged the engine or maybe the landing gear could collapse on landing, but engine damage often resulted in a fire, and the linen and dope tended to go up like a match soaked in lighter fluid.
I've seen many pictures of forced landings, but the majority of them show some pretty serious structural failure, from fuselage fracture to wing spar failure.
Best thing would be to have a look around some books on WWI fighters or Air Battles, they often have great photos (often grainy, but full of possibilities) and you can get ideas from them.
Cheers,
