Peter V'landys is prepared to put the NRL grand final out to tender, with Sydney, Brisbane, Perth, Melbourne, Auckland and Christchurch among possible bidders.
According to people familiar with his thinking, the NRL boss is serious about a Super Bowl-style bidding system, and Adelaide could also compete.
Accor Stadium hosted a sellout decider, but that does not guarantee Sydney future hosting rights; V'landys believes a move could bring major revenue despite backlash.
Daly Cherry-Evans, 37, became the oldest premiership winner after the Roosters beat Newcastle on Sunday night, and his 15-year gap between title wins is a record.
Former Sea Eagles teammates Anthony Watmough and Mark Carroll have criticised him before, but both acknowledged his grand final achievement.
Asked on Fanatics TV if Cherry-Evans deserved another title after Manly's 2011 win, Watmough replied: "Umm, umm, umm … look, he's done a lot for the game so, yeah, I'd say he does,"
He added: "I don't want to be nasty about it. I don't like how things happened (at Manly) but at the end of the day he's played a lot of footy, he's done a lot of good things for the game and been an ambassador. He's done enough to warrant going out on a high."
Carroll, who previously said Cherry-Evans had damaged his Manly legacy by leaving, congratulated him in The Nightly after his decisive field goal.
"I am willing to lay down my arms and congratulate you on a fantastic win and fitting end to your NRL career," Carroll wrote.
"As a sign of peace, I'll even throw you a farewell barbie if you want to drop around to my place before you leave for England. And the first round of Spuddwisers are on me."
Roosters star Mark Nawaqanitawase, who has switched to rugby, scored twice and said: "It is sad to go but this is going to last me a lifetime."
He has represented Australia in both codes and competed at the Olympics; his next ambitions include the home World Cup next year and the Bledisloe Cup.
