If you got your heart set on it, then you can go whole hog and bring in AKB0048. (Or, as it's properly stylized, AKB∞48)
What's great about this is that all the characters, while voice by members of AKB48, are otherwise entirely fictional. So this way it will make things a a little easier WRT intellectual property within the setting.
BONUS: This will fit into the setting in that they legitimately have their own freakin' space ship (and it's pretty damn awesome looking, too) from which they conduct guerilla concert performances.
Yes. I mean "guerilla" in a literal sense. They will go into authoritarian territories where they are banned by the government (like how the USSR forbade music from Western nations), and put on a show for their fans who are stuck behind enemy lines.
With this, you can not only have Aimi Eguchi there, but have her actually playing a very real part in things.
Other Thoughts: since Aimi Eguchi is artificial, then why not have her be a Piffle Project that got a little out of hand? This will give her the distinction of being the Forever Pop Idol - she'll go on hiatus for years and years at a time, letting the newer girls have their time in the limelight, then come back from some sort of soul-searching journey, and sporting a bunch of new sounds and new ideas. This way, her existence as the "Forever" idol of AKB0048 never gets old. Instead, her breaks from the biz are accepted, and her returns to the stage are eagerly anticipated.
