Hoopa pulled alternate reality versions of the Creation Trio and Rayquaza out of his portals. Also if the Hoopa movie alone puts Mega Ray to the level of the Creation Trio that would simultaneously chainscale The Mega Latis, The Kyurems, The Primals, Deoxys (possibly by scaling from Mega Ray in ORAS and Origins), and Regigigas to the Creation Trio which wouldn’t make sense at all
All of those you mentioned either fought alongside Dialga and Palkia or were there simply for transportation in the case of Latios and Latias and weren't exactly fighting
Deoxys (possibly by scaling from Mega Ray in ORAS and Origins)
Deoxys does NOT scale to Mega Ray, we literally see it fight on par with its base form and when Rayquaza goes Mega during the Delta Episode he oneshots the meteor it was piloting
Kyurem tanked hits from Rayquaza and Groudon tanked a hit from Kyurem the rest should scale to each other that’s the scaling. Deoxys canonically fights Mega Rayquaza in ORAS. And the Latis helped Rayquaza make a tornado that held back all the other Legendaries in the Hoopa movie, that movie’s scaling is weird and should be ignored not to mention that these were literally alternate versions of the characters
Chainscaling in Pokémon gets extremely messy since it has so many different iterations, canons, and alternate versions so compositing all of them doesn’t really work unless the feats end up super consistent with one character, and Mega Ray = Creation Trio isn’t consistent or substantially backed up by lore at all

Honestly it really just goes
Mewtwo = Deoxys = Rayquaza
Mega Rayquaza = Dialga/Palkia
All of these are literally on screen (panels in Mewtwo vs Deoxys' case) fights
Now, is Mega Mewtwo = Mega Rayquaza true? If Mewtwo = Rayquaza is then i don't see why not
