I would find it incredibly dubious for it to be Tama's fruit given he never set up its temporary fake name in the actual manga. The mystery doesn't work without that and if he does it super close together it comes off as cheap. So to me this is about as silly as people that thought real Oden was alive.
Like a story can go many ways but good storytellers generally don't screw themselves over intentionally if they don't have to. If it was Tama's fruit this would have been easily avoided with like a dozen of chances of revealing its temporary fake fruit name in several chapters before it and yet Oda didn't choose to do so.
As always I'll argue in favor of Oda's competence on things like this and will believe that he wouldn't commit such an amateur mistake for some meaningless flat landing reveal out of nowhere.
To add I find it weird because the way the mystery was set up with a name change being the mechanism of the tease. It's another point if Oda wanted Tama's fruit to be the special fruit why did he choose that as its tease. He wouldn't need to make a reveal that has a name change tease he literally could have avoided all of it just rephrasing the scene slightly different.
I will say one thing though X Drake attacking Amigasa village under Kaido's order still kind of an open question though.
