i fear it will take a lot of time until there's an update available for pagekit. 
Hm. That's possible - and uikit 3 isn't stable yet...
Well... To answer your initial question: Isn't that something webpack could do?
i'm not so familiar with webpack and it's features 
Oh I wasn't, too. Well - I guess I'm still a beginner 
But when it came to move away from bower, webpack was quite a handy tool.
Maybe you could do some tests with it? For sass there's a loader available: https://github.com/webpack-contrib/sass-loader
As I'm interested in getting new skills with webpack, please share your thoughts and your progress here
I am also interested in this. Actually I am already waiting for a long time they'll update Uikit and Vue JS. At present, a pagekit update is to expect not until summer autumn in my opinion.
I did some research about this. To update vue js to v2 isn't possible without hard reworks in pagekit.
For Uikit you habe to write an own build script for compiling less or sass. Javascript files you can already fetch with webpack.
As I am neither experienced with less comping or have know how with webpack, I didn't take this steps. And to adopt all this skills I dont have time currently.
