i don't think so... I think it's a step forward. In AKB, she's just a back row senbatsu member, in JKT, I'm pretty sure she's gonna be JKT's front row senbatsu member, she'll get important role in JKT. Became front member means more screen time in TV show or even single PV. It means her popularity will increase. More popular she get, means there'll be more peoples support her. More peoples support her (I hope) will make her vote in Election increase.
And about new challenge, I'm pretty sure she (and Haruka as well) will get Big Sisters role in JKT. It means they'll carry more burden in their shoulder. They (Akicha and Haruka) must lead this new-born-and-still-need-more-experience group to take a step forward. They have to do something like Miichan did in Shukan AKB, promoting JKT, make more people know JKT and such thing.
I'm sure, Akicha (and Haruka) will send a lot of positive energy and help this group a lot.
