I mean, it's a decent theory, and where Nakomi is concerned, pretty much any theory is valid (even the !Future Avhienda theory, which I personally don't agree with). I came to WoT through Sanderson, having been at first a Cosmere Fan, so I can't always distinguish what Brandon's little touches might have been, because I'm just so used to them. TBH, I always kind of got more of a Hoid vibe from Thom, as opposed to Nakomi.
