Anthem is one of my inspirations, too. My suggestions if you want to make the attributes more about the pilot is to focus on what the pilot is doing while in the exosuit.
For accessing the power of the exosuit, I'd go with Overdrive, or maybe Redline.
For accessing the suit's speed, I'd go with Reflexes, or the name the responsive system is sometimes referred to in fighters, Livewire
For the methodical use of the exoframe I might go with Accumen.
