Seems like a good idea, considering the fact that the conventional explosives in TPT are ridiculously weak for some reason, we need a stable (ie: not THDR or DEST) high pressure/high temperature non-nuclear explosive. Making relatively realistic nuclear weapons would actually be rewarding. Having a ton of extra fire/smoke isn't really needed, it just needs to release a much higher amount of heat/pressure than any of the other conventional explosives.
Off topic: I remember someone had made a mod a while back that allowed you to set the destructive force of bombs using CEXP or some other element. Would be good if it were added to the official TPT++.
