I actually had my own Avatar idea that Lily would hate: an Avatar that was born into one nation, but raised by another.
I'm working on a story for her, but she's the fire Avatar, abandoned as a baby because her village was burned down by Avatar hunters(still working out the details). She's found by a passing Water Tribe ship, and adopted by the family, who just lost their own child.
She learns waterbending first, but when she's older, pirates attack, and she suddenly becomes able to firebend, kicking off a massive identity crisis.
I think Lily would hate it because it has complex questions to answer, and no sister fetish, but what do you think?
I mean you said it, deeper than a kiddy pool without a sister to snog, so already lost lorch miles back. I like the concept as a good way to inject a bit of angst into completing their training. I'd certainly keep working on it, but you're in the right direction.
