Meanwhile, I came up with an AU idea that I'd like to post here on Tumblr (and if I'm lucky, make a one-shot of the AU):
The title itself is misleading, as it wouldn't include all seven princes; Pino, Noki, and Kio would be excluded from the role of the three Heathers and Veronica. And I know the two concepts are contradictory: a group of heroes and a group of popular bullies, but I find it amusing (not in a bad way).
Merlín, Arturo, Jack and Hans = Heather Chandler, Heather Duke, Heather McNamara and Veronica Sawyer.
After much thought, I decided to change their colors as well, that way they would better represent not only the character they portray but also match their original colors.
It's clear that Merlin would be H. Chandler. He's the leader of the superhero group, so why not make him the leader of the teen group? While Chandler's color is red, in this AU Merlin's would be blue.
Red would be Arthur's, with H. Duke as his representative. The color is originally green. This decision stems from Duke's envy of Chandler, and upon her death, she didn't hesitate to take her place as the new "queen bee." Arthur's supposed leadership rivalry with Merlin is also noteworthy.
Having said those two points, I'd like to move on to Hans. His color is green, but I'd be in Veronica's shoes. Compared to the other three, Hans isn't arrogant or narcissistic, although he's still superficial. But, like Veronica, he's the one in his respective group who seems to be the level-headed one, the one with common sense who knows what's wrong.
And finally, Jack. He's the only one whose color I wouldn't change, since, like H. McNamara, he would be yellow. I have a complex explanation for this decision: Jack was raised with humble values, but after his mother married a wealthy man and gained a place among Merlin and Arthur, he felt somewhat obligated to do the same, fearing they would exclude him if he didn't. Like McNamara, he's the kindest of the trio, but he participates in the same activities as his group. Because of this, he hides his concern for his appearance.
Now, if anyone is willing to collaborate a little on the idea for this AU, or even start drawing them, I would be happy to see that I wouldn't be the only one who envisions them singing Candy Store ToT.
