Obviously, the girls can compete with that. It's called "because the plot allows them too". If you're asking if Jupiter will be out-staged, well that will depend on your producing skills.
*coughbackflippantyshotscough* XD *shot*
But seriously, I know they can, simply because the game will allow you to. Making a game where an opponent is unbeatable in any way is like the makers stepping on their very fans. D:
An unbeatable opponent would be really bad, and then there wouldn't really be a point in having the opponent there in the first place anyways. We all know that in the end, no matter how awesome 961 may be, 765 always wins and Kuroi fails. Does the man have any pride? No. But do his idols put on great performances? Yes.
I was thinking about the girls doing backflips and the...*cough* panty-shots, but them jumping around in high-heels and all kinds of other crazy outfits...it would take quite a bit of skill.
Gymnastics Hell Training time?I could picture Makoto, Yayoi, and Hibiki maybe succeeding because they're more athletic, but Haruka? No, just no. It would be cool, but...given her history, it wouldn't turn out well.
