Am I the only one who feels like the K-on girls could be the children of the canon Love Live couples?
Edit: Even though K-on came first, and are actually subjected time.

Umi and Mio are the same person so it's not possible ._.

I don't know how Umi and Mio could be a same person....though
I think what he means is more of a wild imagination (mousou) play here, in a creative sense.

I kinda see what you imagine there, correct me if I'm wrong:

NicoxMaki -> Azunyan (twintail tsundere)
NozoxEri -> Mugi (ojou-sama type, and that yuri-sense/radar/whatever....hail! takuan! :))
KotorixUmi -> Mio (the shy type)
RinPana -> Yui? (Rice/gohan....I guess...)

I don't know if HonokaxTsubasa could be related to Ritsu though...
