Time skip, make her 2.5x thicker, cause she uses body fat for her power.
Replace encyclopedia belt with a simple armguard tablet that also uses her voice recognition. Probably can scan materials too.
Skimpier outfit, straight up just a latex bikini, but she wears a cloak to cover herself and it functions as a shield and maybe a glider, same high tech bullshit as Batman.
Give her some martial arts combat training so she can actually fight and doesn't have an anxiety attack every time in combat.
Partner her up with Deku to learn strategies. The two are both "smart and strategic leaders" but she fucking sucks at it. Doesn't help she lacks charisma; she functions best to always be Deku's co-leader, really.
Just make her romance with Todoroki canon already and have a little drama on that angle, such as her involvement with his family issues and when Dabi is inevitably confirmed his elder brother (it's fuckign stupid but will happen).
