I remember having a brief conversation with Lorne about the Oddworld gods and deities and such, there are indeed more deities than just Shrykull floating around.
However as for theories, Meeches weren't in AO, Scrabs and Paramites were, so Shrykull resembles the creatures we actually see for more than a couple seconds in the intro, it's as simple as that. I'm sure had they been included they'd have their own temple - but they weren't so there isn't such a temple.
