Native Widget Source Code?

Is this available to edit?


I'd be interested in the weather widget if this is at all possible.

Ages ago I was looking to tweak with the internal music player widget and I feel like I found some lower level representation, still in json. This might have just been the widget as json(can't remember) but the idea of being able to tweak some high-level stuff in native widgets has me hooked. In my case I'm trying to edit the dock widget's long press action - I'd hate to reconstruct the whole thing from scratch but it seems that's what I gotta do. If you happen to make any headway pls lmk.
