She'll get content soon enough. Pretty sure Morgan will be included in the Band Harem.
I don't think so, she's already part of the pixie threesome and considering that's the only interaction between kleo and her, it would make more sense to have a new harem, separate from the band (considering Anna also dated girls), or a MC childhood one with Alexis, Minami and Kylie. Besides, her story is basically only half done and I suspect an update focused on her might be in the works.
Personally, I wouldn't mind an Emma/Morgan route, where Emma is the only other character (apart from MC) who doesn't realize Morgan is a girl, with sneaking around or both pursuing her be an option, should her masculinity stay high.
