Proto.io has had stateful components for quite a while now. Never used it to design things directly in. But quite fast to slap up a prototype with sketch imports, or pngs/jpgs if too complex for it to handle without lag.
From what I remember, you can chose the states of the components on page load, then add interaction on hover / Click / whatever that sets different states on any component(s) on the page, or even on other pages. Might be worth the look.
Though don't look for symbols overrides or the likes. It's not going that far.
