I agree with what most everyone else is saying. If I had to assign exact positions I'd say this:

Staring: Emma, Hook, Regina, Henry, Zelena

Guest: Snow, Charming, Belle, Rumple

And then of course we get some new staring cast, either people who are guests now getting moved up, or entirely new characters coming in.

As for how Snow, Charming, Belle, and Rumple get moved to guest, I think Snow and Charming just fade into the background taking care of Neal and other SB stuff, Belle would also still be alive although maybe leaves town with Gideon, and Rumple will be killed off, resulting in a new character becoming the Dark One (and this character would probably be staring in Season 7). All four would still appear occactionally in flashbacks, and Snow and Charming occationally in present day as well.
