I think Shutenmaru will definitely do that.
Orochi's character is definitely inspired from Akechi Mitsuhide - who betrayed Oda Nobunaga, planned his assassination, and took the Shogun title from him. 13 days later, he was involved in a battle against one of Oda's retainers, Hideyoshi Toyotomi, who learned of Oda's assassination and planned to avenge his death... After retreating from that battle, Akechi was killed by a bandit leader.
(I mean, even the names are similar... Akechi, Orochi etc..)
The bandit leader in Wano is none other than Shutenmaru.
Though I'm guessing in this case, he'll probably save Momo and Hiyori from Orochi and kill him in the end.
