But you can update a semblance - look at Blakes clones. In the early episodes, they simply disappeared. In No Brakes, however, they left behind an inky black cloud that obscured vision for a moment.

I've always worked on that with practise, your semblance range can expand, the duration can grow, the effects can be more powerful. And as for new techniques - well, a persons usage of their semblance is only limited by their imagination and aura control, really. Think of something new, and practise it until you can pull it off, and viola. As long as it desn't go against the base of the semblance itself and doesn't circumvent the limitations (like a semblance for clones that can't make sound suddenly being able to make sound) then the possiilities are endless.
