Probably not since she would have other commitment. Plus she has not forgotten about Laboum.
Also she would be uncomfortable with older musicians who were following a different line of music from her.
Someone at least 40 years old should be running the show, in my opinion, although she is over 40 (1,340).
What has Laboum to do with Sketchbook?
As to her and Sketchbook, it has been a running joke for long,
Last year she had an whole extended Sketchbook episode dedicated to her which she converted into IU's Palette.
Then she called Palette as the sister show to sketchbook when she hosted Itzy.
Then Lee Seunggi on Sketchbook joked that she is gunning for YHY's seat.
I think she will have YHY's support of she does want to take it up.
As to older musicians, given her Flower Bookmark, I think they will be happy if she brings them back to limelight.
The question is only on her schedules and whether KBS can afford her.
And whether it is a good move for her own career.
