I have several ideas, but it is not simple.
The problem is the original parts at the moment.
The plastic on top of the slider break easy and is not a part you can find easy.

I think I found another car where the plastic is used but I am not sure.
It is rear skoda doors (favorit and others)
Not electric but probably same springwinding and plastic hook.
I will order one to find out when I ever find time.
I think it is possible to use partts of it and meke it elektic with motors from sets where you can make handwinder electric. (it is all a gues yet)
