It's pretty clear to me that Signature Attacks of CoC Users are Fated to be Inherited (Either by other CoC Users or Others)
It's like their "Will" lives through that Fighting Style
So sooner or later, We will see a Someone else using Sengoku's Signature Attack, Zoro's Oni Giri, Big Mom's Ikoku, Kid, Rayleigh, Dragon ... etc
Drake's Fighting Style doesn't resemble Sengoku's at all, so No
It needs to be someone who's Signature Attack is same as Sengoku's
We've already seen Drake's & it's X Calibur
I think Urouge is the one who gonna Copy Sengoku, He fits much better & has the Physical Strength to do it
