Yep.
Grand Fleet, definitely yes.
Pre Timeskip, Luffy challenged the WG with hitting a CD & got destroyed by an Army of Kizaru, Kuma, Pacifista, Sentomaru, Vegapunk name dropped.
Post Timeskip, Luffy actually spent time in the New World & can match an Emperor in combat, is even called as such.
New Arc? Egghead Island. Arc of Vegapunk, Sentomaru, Kizaru, Kuma, Seraphim which are also PX.
Now do you really think Luffy will lose?
Especially his actual Rivals in Yonko ( Shanks & BB ) not those Pretenders ( Kidd & Law ) got weeded out?
A CoC User but Hakilet Kidd got weeded out by an insane CoC User.
Just like how a DF Spammer but Hakilet Law got weeded out by an even better DF Spammer with 2 DFs.
And guess what?
Lucci, Bonney refuse to accept Luffy as Yonko.
Lilith thinks SH are Trash and is then reminded by Shaka that Zoro or Robin will take her down in a matter of seconds.
Greenbull underestimates Luffy and thinks he can walk up on him and take his head back to Akainu.
Shanks shows him his position & that applies to Luffy/SHPs too.
Remember before Wano? When we had Shanks say it isn't time for Luffy to meet him yet but it's soon?
This is the time - and that's gonna be shown by Luffy's fate right now being the same as His Actual Rivals, the Yonko (Mihawk for Cross Guild) & not the Failed Pirates with their Dreams crushed - basically future Warlord material.
This is the time Luffy is for sure differentiated from the Supernova, he's basically a Yonko now. The entire World is underestimating him & the Strawhats (starting from the Absurd Equal bounty to Kidd/Law) will legitimately establish themselves as a Yonko crew that Marines or anyone can't fuck with or underestimate - Luffy & the SHs are all getting Another Bounty increase with No Powerups needed in these fights.
They are gonna show off & establish their Reputation for crushing this Armada & taking what they wanted for themselves.
Oda is establishing the Final Players for the Race to One Piece & that needs Victory and Hype for all the 4 Factions participating in it.
