Maybe
London Stadium and Wembley in size are vastly different from Spurs or Emirates which are significantly smaller to compare. I don't see SOAD coming over to just do 1 Emirates show. Stadium show at Emirates maybe at a push, stadium shows which it was kinda suggested above they could do multiple dates, no. SOAD didn't have a UK number one with any of their albums releases compared to 3 in 5 in the US. They subbed Reading after headlining Download twice and only just survived still headlining in 17 so they weren't even one of the few metal acts to be considered big enough with enough crossover to top spot both like RATM, Metallica or LP have to name. I love SOAD, my favourite metal band but they've never even done a proper UK arena tour.
i think Muse are out
I still don't close the doors to Neil Young (From all the names that may still come, i still believe it is the only one that will sell out the festival)
The Last Dinner Party, maybe
