Personally I believe scabbards are out for the rest arc, even if they somehow get up I doubt they'll do much. Their big moment was against Kaido
Now that Onigashima is going to Wano, the opportunity for the scabbards to get relevant points has increased.
Like even if they are extremely weakened, now that we are retiring to mainland Wano, we can get smaller plot points like Kin'emon like protecting His wife tsuru from someone, then like Kanjuro could return and try to go after Hiyori but kawamatsu and Denjiro fight him even when they are very weak, and of course Orochi returns and the weakened scabbarda fight him
Their big moment was Kaido but it could be like Law in Dressrosa who could still help out a bit after getting severely beaten by Doffy. And Wano has enough loose plot points and many enemies that the scabbards can find something to do
