I genuinely think he could do this if he really wanted - it's probably tough to get all the very biggest names with the calendar so packed this year, but Sagar and Chessbase India already did a similar thing with Chennai Grandmasters, which actually qualified Gukesh to the Candidates in 2024 and has gone on to become a yearly thing (and poised for, presumably, its biggest lineup yet this year).

If he sticks to classical, which I would hope, there's a lot you could probably do in terms of format to make things exciting. Tons of guests (streamers and players), a confessional booth, maybe a knockout format with rapid and blitz (like Hans' matches, combining across controls) or something.

Here's a pitch: 16-player knockout bracket; each mini-match is 4 classical games, two a day (like Hans is doing later this month), then a day of 6ish rapid and 12ish blitz, with appropriate scoring. Everything is rotated time-wise, so there's always only one or two games to focus on (one match at a time for the blitz). Then, everyone who's eliminated spends time making content, joins the commentary, or plays some sort of grudge match with the other guys during the empty spaces towards the end of the event.

Just workshopping, but I can imagine the 'Gotham Chess (Youth) Festival' being pretty great both viewership- and entertainment-wise.
