Maybe but King needs to show some another lvl feat if he can give an extreme diff to post rooftop healed Zoro. The experience Zoro had, the COC thing and Enma put Zoro in low top tier so for that King needs to shine af. Expecting a lot from the FM of WSC.
The safest best is that Oda will make the fight hard by having Zoro just healthy enough to fight, but not back to full health.
Of course the other option is to have Zoro being almost ok and truly power up King by giving him CoC attacks for example. But up until now Oda doesn't seem to care enough about King to do that.
