Dark Order should definitely hold the Trios at some point. Should be a given I'd think.
They'll probabky want bigger names for first champs but I honestly don't envision the belts being that prestigious, or at least I wouldn't try and book them that way.
My ideal 6 man titles in AEW would rarely be on Dynamite, maybe a bit more frequent on Rampage, and predominantly defensed on Elevation or Dark fairly often with probably a lot of changes and not many long runs. Just to give the shows a semblance of stakes besides rankings. And Dark Order would literally be the perfect team for it lol they even joked on BTE today about doing the firebird rule since there's 4 of them
