AAAAAAAAAAAAAAAH! I'm sorry. It's just that you made all of my dreams come true.
I would LOVE to see Nick as one of her older siblings. They're sort of supposed to be a hodgepodge family so the fact that they don't look exactly alike wouldn't matter, and he would have another baby sister (this one adopted) in amarissa.
I would also LOVE to see Megan as a really good friend. Like, next-level, people think they're a couple all of the time friend. Depending on how you like to play her they could also be the sort of people that do wind up together off and on occasionally but it never quite works out and they just keep doing a yoyo type thing without it ever getting weird enough to put them off.
