I dont think that will happen. The battles Oda offpanels either lead to nothing (Sanji v. P1) or are hidden for the purpose of retaining mystery surrounding a characters fighting ability (WB remnants vs. Blackbeard Pirates, Sabo v. Fuji, RA vs. 2 Admirals, Aokiji vs. Akainu). You WILL see these characters fight, but its a matter of patients. I dont forsee the forthcoming Wano chapters offpaneling anything.
Kiku vs. Kanjuro imo was offpaneled because imo, Kanjuro is still alive and still pulling some sort of trick. And in that case, their battle led to nothing. Either that or he is going to switch sides by change of heart and have significant moments helping the allies, thus preserving his powers for big moments.
