I think your good with your 6*. Might want to rank them when required. If you do have anyone you'd like to, anything you think someone might work well, then yes.
for 7*, my suggestions would be: Mystic: Kushala. She's really really great. My 6* gets used so much, would definitely rank her if I had her as a 7*. Mutant: Dazzler, Sinister. Lots of damage. Quick fight champions. I think they're great choices. Tech: Shocker is great. Science: Spider Punk is super slept on. If you get accustomed to his playstyle, man he hits hard. Cosmic: Your options are Gladiator, BRB, and Adam. 2 of them have very aggressive playstyle, which I cannot work with. So I think it's personal opinion, all of them are great though. Skill: Cheelith slaps. Elsa is great too, but its a personally biased answer, so you can take her around for a spin, (TMI she spins while dashing back), and you can decide what to do with her.
I've given the kind of input I would like to receive when asking for roster upgrade suggestions. My bad if it still has a lot of them to work on.
