I honestly like the idea of Harry Osborn coming back from the dead as Green Goblin but with a supernatural twist to it. Like it comes out Green Goblin split off from Norman somehow like a sort of spiritual split of some kind and brought Harry back wrong through dark magic or something like raising his spirit and putting it in a modified clone body. I like this idea as it'd be the perfect karmic problem for Norman as the Golden Goblin. I can see Goblin's spirit manipulating events as revenge for being rejected by Osborn and deciding to raise Harry from the dead as a twisted form of payback. I think for Norman trying to be a hero his son coming back and being under the control of his evil persona would be interesting to see. Also Harry as a villain for Norman in my opinion would be very interesting to see given Norman's many failings as a father. I also like the idea of Norman starting to see Goblin's spirit manipulate Harry and saying things like "You know Norman I'm beginning to think Harry is a son of mine after all."
