Considering my next giantess RP prompt...

I'm considering one idea I've been kicking around for a while, centered around a group of girls who gain size powers and use them to have fun with the world around them. This one would probably involve a more specific group of characters, and I might expand the cast over time. The story could either take place at the beginning of their rise to power, or some time later when they've established their dominance over the world. The RPer could play a normal person who comes into contact with the group in some way or another, one or more of the girls in the group, or a new girl who befriends them and gets to join in on the fun. My current ideas for characters include but are not limited to...

-Rich/Popular girl. Tends to look down on other people. Probably responsible for the funds behind their growth.
-Nerdy girl. Rather shy, even as a giantess.
-Excited, somewhat ditzy girl. Thinks tiny people are super cute, but can cause trouble through her spacey nature.
-Tomboy. Girl with a crude sense of humor who loves toying with tinies in gross ways.
-Chubby girl. Loves to eat, and enjoys snacking on tinies.
-Athletic girl. Loves showing off her muscles and overpowering tiny humans.
-Goth girl. Comes off as apathetic to her situation. Kind of a wild card in how she acts.
-Younger girl(s): Probably the younger sister(s) of one/some of the girls. Sees being a giantess as a game, and the world as her playground.

Feel free to offer feedback and suggestions as to what else I could do with the idea.
