Yes, for sure! Violet and Elastigirl are going to be the two that are a little more difficult to do... I'm thinking for Elastigirl, one way that would make sense would be to have her punching/kicking behind a screen that has an elongated arm/leg and another person's hand/foot hitting whoever she's trying to hit on the other side of the screen... that would be a little more difficult to pull off... I'm trying to find a picture to describe what I'm thinking, but apparently I can't find the right keywords haha!
As for Violet, it would probably be easiest and most convincing to put a purple spotlight on her, indicating that she is using her power to make herself invisible, and the rest of the stage is a little dimmer to really sell that effect.
I'm doing my best to describe what I'm picturing going on in my head haha, I'll try and see if I can find some pictures to explain better!
