[Q] Widgets like OPO's Shelf, HTC's Blinkfeed etc.

Is there any possibility out there to make a custom Shelf page for, say Nova Launcher? Like put widgets in a vertical-scrolling page, making a custom Shelf/GoogleNow alike thing? Maybe a "scrollable widget-container" to put widgets in? If not, maybe I might just given you a million dollar idea (patented dont even try lol).
Anyone?
