If her reappearance this season had shown more of a turn to the dark side, I would agree with you, but as is, although she's different due to her association with Merlyn, I don't feel she's different enough that I could see her becoming a completely amoral mercenary for hire. It would take something dramatic to bring about that much of a turn in her character, and if none of the previous events that happened to her accomplished it so far, I don't see it now. Pretty much the only big reveal left is that Oliver is the Arrow, and I don't think that one last lie will be enough, given that its balanced by her now having her own lies, ie Merlyn training her.
Plus all the interviews and summaries about this season have been about how Merlyn and Oliver become reluctant allies, and that can only happen while there's the possibility of Merlyn corrupting Thea. The second he actually succeeds in corrupting Thea, all chance of Oliver ever doing anything but hunting Merlyn to the ends of the earth becomes null and void.
Edited: Plus, the main reason I don't think Thea will become Cheshire is because the longer the show goes on, the more each of the supporting cast needs their own storylines, and there's nothing more Roy-centric than Cheshire. All of the other characters have plots and motivations separate from Oliver now - Laurel is becoming Black Canary, Diggle is a father and has connections with Lyla and Argus, Felicity has a brewing romance with Ray Palmer and ties to Flash and his team in Central City, and Thea has her secrets and training with Merlyn. Roy's only storylines are Thea, which ultimately all loop back to include Oliver as well, so I think Cheshire when she's introduced is most likely to be a new character. If Thea becomes Cheshire, then that makes Cheshire as much Oliver's story as she is Roy's, and that just doesn't work as well for a longterm ensemble narrative. His character needs something distinct, that can't be trumped by bigger ties to another character in the main cast, or else you kill all chance of him ever standing on his own as well as the other characters do.
