I think we're having a slight problem here because for CoDA our powers aren't 'weaker'. Just that the vast majority of their powers aren't 'developed' that is to say the students have limited control of their abilities. That's kinda the whole point of the academy. Straight up buffing their powers won't really do anything since it's the control and usage that they're lacking in rather than actual destructive power. I responded to your suggestion, but we'd still need to create a satisfying villain/obstacle. Something of that scale actually sounds rather satisfying~ this has my vote.
