Maybe Nao can be like George Martin anyhow?
Knowing the characters in K-on!, they're open and friendly enough to welcome a talented person into their group, even if their proficiency lay in working a mixer board rather than a musical instrument.
And, really, I can't see them not being highly interactive with their producer. The music is too important to them. In fact, I think it'd be like how Thom York of Radiohead always closely collaborates with the man that has done most of their album artwork, Stanley Donwood.
