Makes sense to me. the only thing I would say is that when Iyatil uses transportation, it works normally, and that is, by your logic, probably the "minor" elsecaller surge (if Illumination is the minor truth watcher surge and the major lightweaver surge, then Transformation is the minor lightweaver one and the major for the elsecaller, and transportation becomes the minor). They end up going to the cognitive normally. It makes sense for Mraize's enlightened cryptic though, as he can create illusions normally, which is the major for lightweavers.
¯\_(ツ)_/¯
Edit: also
