Not a fan of that personally. I feel like it needs a minimum of one more player to chip in.
Bellingham often has three midfielders helping him which gives him the freedom to pick and choose when to drop deep and progress play in the first and second phase, and also when to be diligent in his defensive work. Against Osasuna, that was Camavinga, Modric and Valverde and he had an aerial presence in Joselu that acted as a foil for Bellingham's offensive forays. Against Napoli that was Kroos, Valverde and Tchouameni helping their side win the midfield battle. There's a theme of him being supported by multiple midfielders, and he wouldn't quite have that if the profile of the players he was alongside were Rice and Maddison, as the latter also needs that foundation of players helping him in midfield.
With Maddison, not only is he supported by both Sarr and Bissouma in midfield, but there's also the positional play of full backs Udogie and Porro coming infield which greatly enhances Spurs' midfield dynamic.
However, if he did experiment with that midfield trio in the final two qualifiers, I would prefer it, if he utilised Walker differently to how he's currently being utilised, and have him playing more infield to help Declan Rice. Additionally, England would need attacking options in Foden/Grealish or even Cole Palmer to take greater responsibility in helping England dictate the midfield .
Otherwise, the personal preference I was alluding to wouId be to adopt a slightly similar formation to Real Madrid with Saka fulfilling the role of Vincius Junior, and it would allow Bellingham and Maddison to have two players (Rice and one other deeper midfielder) helping out in midfield, and I would tweak the system to include an inverted full back to provide additional assistance. Would like to see more trial and error for Rice's partner, with perhaps Ward Prowse as the poster below me suggested, and I haven't watched Connor Gallagher at club level this season, but the Chelsea fans appear to be bullish on him now. Then after the tournament, take Archie Gray from Leeds under his wing, as a wildcard and really give him some council. Would love to see Rice with Archie Gray in a set up with players full of international experience to help him come into his own.

. I hoped we would move in this direction with Ten hag instead the bald feck decided us to become a worse version of Mourinho and Ole ball.
