You can still find the old pantheon if you look,
Indeed. I don't know if you've finished the main quest yet,
Mr. Fear, but along with Kyne there are large references to both Shor and Tsun, along with Alduin too, of course.
In the very first minutes of the game you hear Shor's name, and there's also Shor's Stone, a town in the Rift. Shor is mentioned other times as well. Some are never mentioned - Orkey and Jhunal - and others - Mara and Dibella - were also already in the Cyrodiilic pantheon under the same name. Herma-Mora and Maloch are just Nordic names for Hermaeus Mora and Malacath.
That leaves Stuhn, who I believe is mentioned at least once or twice. I just can't remember where.
EDIT: And it makes sense that Orkey and Jhunal are missing. Orkey was something of an antagonistic/enemy deity, and Jhunal worship hasn't been popular in a while. Even
Varieties admits that.
