There is some overlap. I just wouldn't be interested in anything that gives you any sort of physical attribute boosts in the Intelligence perks. If I have a Quin Malory build why would I want anything that deals with physical attributes at Intelligence 9 and 10. I'm roleplaying a scientist and the two top level intelligence perks would just be for physical changes. That just wouldn't fit my build at all. Two perks that only boost your stats when you are in a really bad situation. You invest in medicine early on so that you aren't in those precarious situations. Just a waste. Especially when all the lower level perks are so much more practical.
I personally think that I9 deals with nukes and nuclear power. That would make more sense. Even Cyborg makes more sense than "Atomic", because at least it is tied into science.
