How to set only stroke to default graphic style in a script?

When the shortcut D is pressed, the default fill and stroke are set. With similar behavior, I want to make only stroke exactly the same as the default graphic style, without changing the current fill. This is probably not a feature in Illustrator, right?

Not only making the main properties similar, such as stroke width, but also making the appearance exactly the same. Of course I know that script can't handle the appearance, but I'm trying to find a path to achieve this in some way, such as dynamic actions or applying graphic styles. If it can be done with normal Illustrator functionality, that's fine.

Any ideas?
