I'm a bit behind on the discussion, but I know y'all were discussing Sanji "accepting his Germa side," which would result in him awakening CoC, or that Sanji has been holding himself back out of fear of becoming like his brothers. But I'm not really sure I agree with that.
With regards to "Sanji accepting his Germa side," personally I don't think that's negotiable if I'm being honest, and if anything I think it'd be him going backwards. We've already moved past that in Wano. Sanji accepted what he had become, weighing the pros and cons with regards to how his awakening would benefit Luffy and the crew, but reached the conclusion that he wasn't going to allow Judge to have any more influence on his destiny than he already has - which was the whole point of him destroying the raid suit. Then fast-forward post-Wano, and Sanji, whilst being able to use the perks of Germa, is still able to retain his emotions. Sanji losing his emotions, for instance, isn't gonna make him stronger than he already is now - he already has all the perks his brothers do even without that caveat, and hell, PoL in itself can only be a thing if Sanji retains his emotions.
Also don't think Sanji is holding himself back out of fear. There's no reason for Sanji to be scared of using his Germa abilities since he's able to switch in and out of Germa mode. Moreover, when Zoro asked about this very issue at the end of Wano, Sanji himself said that the issue had already been resolved.
Lastly, I think there was another post about Sanji's selflessness potentially hindering him from being a conqueror, and again I'd have to say I disagree with that. In the first place, why is selflessness somehow not conqueror-like? We've had Zoro put Luffy before himself on two occasions already, and no one questions his Conqueror credentials. If anything, I think Sanji's selflessness is one of the things that makes Sanji "Sanji" - it's one of his strongest points, and it will honestly suck if that changes. I have a strong feeling that said selflessness is a key reason as to why he's able to use PoL.
Anyways, on the whole CoC thing, the only thing that's standing between Sanji and CoC atm is Oda.
Sanji doesn't need anything to change about his character for him to become a Conqueror.
