Outside my locked three of Yve/Holly/Jojo, let's see;
Brook, Fabio, JimmyT - just no.
Marty - I actually forgot about Marty till I finished this post. Which just about explains why no to a cover spot.
Jane, Erica, JimmyJ, John - yes they have each been stars one way or another, but too early to impact once you remove the LL stuffs.
Jill, Dan, Russell - each would actually have a shout to be on there for good floater/UTR play but end-result is nothing really worked out for them or enough big moments to put them in top six. In another game perhaps, but not enough against this cast.
Chase, Ted - Yes big characters and heavily involved in the pre-merge portion boots of Brook/John/Fabio etc, but Jake & Yve kinda fill that slot plus more, even if Ted/Chase had the bigger hands in them.
So for me that leaves these four;
Jake - Finalist, emotional, underdog at one point even wanted gone by his allies. A few clutch wins plus an idol. More of a power player than anyone, including himself, is giving credit for.
Ken - Finalist, "spearheaded" some big moves (or where they happening anyway?) both successful and not, would have been a boot over on NuNuPalena and has actually had quite the cochroach arc what with constant targeting, two idols used on him and the talisman.
Tyrone - Yeah I'm definitely in the minority here, and his early game wasn't much but loyalty to his alliance,
buut since merge round so much of the game has revolved around him. Him not wanting the talismans and running the targets back to Jo & Ho, surviving the tie, him getting the talisman in the end

His arc of goat-being-dragged to Jury threat boot. I think his unlikely hero arc makes him worthy of a spot.
WendyJo - Now I know Mia won't like this one

But again, so much of the game revolved around her. Most importantly Jolanda's "flip" and the knock-on effect. Also she was totes the cause of the 4-4-4 split. Her wanting to flip so bad. All the NuNuPalena madness that never came to fruition. The cross tribal alliance. the list goes on.
So yeah, for me; Yve, Holly, Jolanda for sure, plus three of Jake, Ken, Tyrone & Wendy-Jo. I guess if one of the guys locks the win they should be a lock for the cover spot too
