I'd make a shojo block, since most toons are aimed at boys (shojo is aimed at young women). I'd include
PPG (probably first on the block)
Full Moon
Sailor Moon (maybe an hour of this since it's popular)
Tenchi Muyo (closer to the end)
and Trinity Blood on occasion (the manga is a shojo, and it would give some needed action, but because of the short length it could be aired as a special)
any other show for young women (sorry, I haven't watched many). I wouldn't have it heavy on the pink, though. I wouldn't stress "girl power" or anything like that, but I'd make it appeal to females. Maybe every once in a while I'd get a movie licensed (Miyazaki's come to mind) for variety. Sorry we women aren't heavy into action but we do have taste. 
I guess I would call it "Ladies Night" or the like.
