It’s too late at this point, we’re at the point in the manga where all the SH’s are not strong enough to face most of the villains that will come between now and EOS. Usopp, Nami, Brook, Chopper and Franky (somewhat) are reserved for the fodder now.
Luffy, Zoro, Sanji, Nico Robin, and Jimbei are the only ones we really need to see in full blown fights. Jimbei because of his strength and Robin because of her bounty and her overall importance to the general story.
