Alternatively, is it feasible for someone who has no prior knowledge of modding/scripting to copy the Oblivion spell's script effect over to a FO:NV item that I could activate from my inventory?

I'm fine if I have to activate an item to take over. I had a mod for Oblivion that added a spell that did this and was hoping I could get some kind of similar feature in Fallout. There used to be one on the nexus that did this I think, but it's been removed it would seem. I have tried looking for hours, and maybe I'm just not searching properly but I can't seem to find a mod that does this. I would really appreciate if anyone could help me find this.
