Zoro will be the obvious choice as next MC and pretty sure even Oda would love to make us follow his adventures like in Wano.
But if you think, we will see the other SH you are wrong. With luffy, Oda needs to show others SH because they are part of the crew. With Zoro, Oda doesn't need to give a fuck. It will be a solo adventure 100%. Zoro will leave the crew for sure because he doesn't want to put them in danger with his adventures and doesn't like to lead.
But if he decides to lead the crew, they will follow him for sure, they are all friends first of all.
And he is still a WG, aims to be the future WSS, so they ain't really losing something famewise.
Sanji will stay for nami and robin.
