I see no point in continuing with Kang. He’s a flop. The public don’t care, Majors won’t play him again, he’s not a credible threat after Ant Man Quantumania and he is just underwhelming after Thanos. The stakes with him are just too low.
I haven’t watched Loki s2 but I read they end it where you don’t need to continue with Kang so just don’t.
Just focus on Secret Wars and bring everyone (Original Avengers, Fox X-Men, Snipes Blade, The Spider-Men etc.), bring an alternate universe T’Challa, make it an epic farewell and reboot.
