Scabbard teleport away and im sure Oda use them later again. In case Sasaki vs Kyoshiro could became true. In that case Nami+Usopp+Izo and Kiku(ofc injuried) vs Pageone and Ulti would fit more.
Same for the other battles:
Raizo with Brook and Robin vs Black Maria would be cool too.
Franky and Kyoshiro(take in mind that Kyoshiro is damaged) vs Sasaki
Kawamatsu could help out Jinbe vs WsW
Ashura/Inu/Neko/and Kinemon could help against the calamity and Kaido. For Kinemon I could imagine him joining later the top again.
With the Scabbard beeing now free, Oda could perfectly use them to help out the Strawhats for their battles.
I kind of don't see how Usopp and Nami can help (without zeus) people like Izo who can disarm King.
Denjiro is stronger than Zoro, a nerfed Denjiro is kind of swole asf still, especially compared to Franky.
Kawamatsu is one of oden's stronger scabbards, top 5 or 6, albeit the top 5 or 6 are a whole tier higher at least than the rest. (Kinemon?, Inu, Neko, Asura, Denjiro, and Kawamatsu are all around the same level, Kinemon is honestly hard to gauge, he only actually fought Law until this, and knowing Law and Kinemon, Kinemon probably just was being stupid and believed Law was on his side, then Law hit him with hax from behind or something).
So if Jinbei and Kawamatsu are needed to defeat WsW, the middle and weakling trio are literally worthless against tobi roppo. It took literally 15 seconds of fight for ulti and page one to defeat usopp and nami, and that's not exaggeration.
Inu and Neko will probably Awakened Zoan Jack, without suulong, but simply it being a 2 v 1 and the 2 having like god tier synergy.
Drake vs Queen before Drake later joins for the real final conclusion (I think the current team vs big mom and kaidou will lose, and killer/zoro will either have to fight someone else after being broken, or are just dropped out of the arc for the most part by the beat down)
Marco vs King then he joins for the fight fight against Kaidou and Big Mom.
The team will lose in the fight fight, then Drake and Marco will join them, along with Hawkins switching sides (who uses his devil fruit to bolster the strength of the good guys), and it'll be the 5 supernova shakky listed as the top 5 pre skip (was build up to this moment) and marco vs kaidou and big mom, and that's how they'll win.
