Nah, that just basically turns them into Sarah/Melanie 2.0.
Friendly banter would be hilarious. MC already has his reputation around campus regardless if you're a himbo or not, due to the leaks
I think that's the general vibe for the Pink Rose/Felicia/Leanne and now some of the Dorm girls. They're ALL just Mel/Sarah personas. And they have to be, or else the bloated Other's route wouldn't work. It's why Sally has her personality and sticks out. Sure, Pink Rose are strippers, Mel/Sarah are on board with the restaurant, and now some Dorm girls are just loose and flirty.
It's what makes Nicole/Lily stand out from Sandy, and Tara stand out from the Dorm girls (Tiffani/Kylie/Gina/Christie/Becky). They're not just flirty/DTF girls.
And for the opposite reason how Mel/Sarah stand out from the HOTs (Arieth/Ashley/Camila/Elena/Quinn/Riona/Heather), though Camila's is in both camps, she gets slightly more fleshed out.
I think Lily represents that ultimate persona of confident, DGAF attitude, but realizing she wants something more. (Whereas Nora is the ultimate, final form of that.) That was the vibe at the end of one of the episodes (can't recall) on the Others' path where the MC messages all kinds of girls, feeling alone. And how lab girl/Cinderella is the normal MO -- introduce a new girl (e.g. Tara, Tiffani, Camila, Riona, etc.), tease them at the beginning, and then develop them later.
But this is getting old, since we're in season 3, and you can't keep introducing girls unless they're just Mel/Sarah personas (Felicia, Leanne, etc.), and bloating the Other's path even further. Which seems to be antithetical to what Being a DIK is all about, and what players expect.
