I respect the take but it's still a show about Boba Fett. This would be like if Mando suddenly took up a chunk of its runtime to see what Iden Versio was doing. Yeah Mando is related to Boba, but it's still a show about Boba Fett, it lacks focus and throughout the show it's not connecting anything. Stuff is related and the fan service is cool, but even stuff like Cad Bane needs to be established earlier rather than at the end if only to pay off to a Clone Wars episode from over a decade ago. It can't all be fan-service. You have to connect the narrative tissue otherwise it ends up like Bad Batch where while cool, goes absolutely nowhere.
What would make the Jedi temple stuff work is if Boba went. Boba hires Mando and Mando knows Luke via Grogu. Mando wants to see Grogu. Boba needs muscle and the Jedi are some pretty strong muscle. They go and Mando has his diversion while Boba gets an awkward talk with Luke and realizes that Luke is still pretty early on in this rebuilding of the Jedi order. He also can't leave because he's the only Jedi there. Bringing in Ahsoka was a mistake since this raises the question as what Ahsoka even bothered to do there aside from be unhelpful and fan-service (she could also be asked to help giving Filoni his Ahsoka action sequence in the finale). So instead it's only Luke and Luke can't leave Grogu. Then you do what you did already with Freetown. The sequence plays out the same with the possible scenario the locals will come to Boba's aid instead.
That would be a way to bridge the disconnect. Boba shows up asking for help, can't get it from the Jedi (or maybe he only gets Ahsoka and it'd have some significance given she has faced the pykes before) but instead he gets it largely from the locals instead. We didn't need to fart around the temple, they could've kept the plot moving while showcasing what Mando and Grogu had been up to. And if they worked at it you could've had bigger payoff with Boba generally being a much nicer Daimyo than the others making the locals more inclined to help him. Boba isn't a hero, but he's the nicest leader they've had in years and even gets the tuskens to help. So Boba think's he's outgunned when pretty much the whole planet answers the call.
