Well I gotta disagree with you on technokinetics, because of the paradigm shift with mutant technology now including gestalts of mutant powers as well as just control of machinery. Tbh, technokinetics should be used a LOT more widely in the books than they are right now, given their usefulness in mutant society just took an insanely big leap. They can effectively merge any group of mutants' powers into a usable circuit by tweaking the way those powers interact, much like how Hope herself synergizes The Five's powers. Like, Taki in S.W.O.R.D. was able to use his technokinesis to merge six different teleporters' powers to act as a single fuel-base for one teleportation gateway....even though NONE of the individual teleporters have any kind of natural ability to boost another teleporter's jumps.
If ever there was a time to make technopathic/technokinetic mutant characters more popular or better known, it should be now, and yet all we've got is Taki and then Trinary making a few appearances here and there.
Also lol at the idea that there's only four technopathic mutants.
You think there are a lot of time-manipulating mutants running around? Hoo boy, technopathic/kinetic mutants have them lapped. Like yeah, there's Wiz Kid, Trinary, Network and Milan....but there's also Tin Man, Madison Jeffries, MeMe, Ziggy Karst, the Reanimator, Key, Broadband, Vesper, Overrider, Paradigm, Zero, Post, Evangelina Rivera, Teleplex, Hexadecimal, Hijack, Black Box, Doctor Goodwrench, Nathan Beame, there's a Wakandan mutant named Xabbu Sulaweyo.....probably a good ten more or so I'm forgetting off the top of my head, lmao. There's a LOT of technopaths available to use.
