It the books Saurons eye and the fire from Mt. Doom are visable from all of north Mordor. So should there be a red blur for Mt. Doom and when barad dur is add to the mod, a red eye in the sky in this region? Just the upper plane not the lower plane like Nan Ungol and Nurn and also Morgul Vale. Note these are places where it would NOT be. Just a little reminder that mordors northern plane is pretty much flat.
