What you present makes some sense, but there's only three things we know for sure about the Stalker:

1. He is a 'rogue Tenno' in an unclassified or modified warframe.

2. He hates the Tenno enough to work for the Grineer, Corpus and Infested. When you are faced by the Stalker in-game, he always tells the player he is after specifically which boss they killed that he is there to avenge. Since he works for all of the NPC factions (and they are all essentially hate each other), the only thing that makes sense is that he is doing it out of hatred for the Tenno, not because he is allied with one of the other factions.

3. He isn't Hayden Tenno.

Sadly, the Stalker is another big gap in what we know about the Warframe universe.

One of the points you made caught my attention; it was the notion that the Tenno may have been made 'mindless' and some developed sentience and rebelled thus their being dubbed 'the Sentients'. It makes some sense if you believe in Possibility 1 in the Orokin Era section. The only thing that makes me feel iffy about it is the fact that the post-humans (the race that would become the Grineer and Corups and thus the Infested) are obviously sentient creatures and they were most likely made by the Orokin as well, so why make one group of humanoids sentient and the other not? It's all a big muddle, that's why the story sections that cover mostly unknown time present multiple theories and stick only with what we could nail down.
