Here's a fun thought

Just imagine an AU where all the main characters' personalities are swapped.

Like Lukas and Petra's

Lukas being the tough and intimidating guy you wouldn't want to mess with that has an obvious soft side that he refuses to show it.

While Petra is the soft one, who is worried so much about her friends, she's not even concerned of her will being.

Or Axel and Olivia

Axel being the smart one and Olivia having the explosive personality

Or just M!Jesse or F!Jesse

I get they are the same character, but the way they're played feels like they each have their own personality, where male is dry and sarcastic all the female is straight up dorky.

Just, male Jesse with me the dorky one and female Jesse would be the sarcastic one.
