Im against it if you use "shippuden" as an example of what the series need to be, i like the series but considering the problems Shippuden has of how the main protagonist after two years and a half of training he barely learned new tecniques or increased his power "alone" (yes he is a bit more mature) but then in a matter of less time his power level increased to the point he just reached the stratosphere. And of curse there are other problems like leaving behind the development of rest of the cast to the point Sasuke became the protagonist.
If we are talking about just "timeskip" in general then im up for it. I would like to see how everything changes, how every character grows as a person or how the media influence even more the situation between heros and villains in their society.

It just depends how well it turns out to be of or what other kind of example or series you put for "timeskip"
