When my Symbols are done in sketch, I can build a mockup very quickly. Have you considered building a plugin for Sketch? I meet with the InVisionApp sales team few months ago. Their phylosophie is to work and augment the current tools (Sketch 3...) instead of replacing them. I thought that it was a good approach. I'd be worried that the designers will be scared by a command line based tool. This will be hard to convince people to move away from Sketch 3. Thanks for trying to improve the designer tools, it's much needed.
