Yes, a custom Android launcher would be able to implement this (though it might be a little tricky to figure out how to make the transition between app icon and widget since some apps don't have widgets, some have multiple widgets).

Given the way the Android community has picked up on these sorts of things in the past, I wouldn't be too surprised if someone creates a launcher that implements this relatively soon.

Try Action Launcher for android (https://play.google.com/store/apps/details?id=com.actionlaun...)

Implementation here is , when you swipe up on an app icon it opens the widget related to that app
