What do you mean exactly by that? You want to replace the contribution side (camera to server) by WebRTC or delivery side (server to screen) or both?

Contribution: there are platforms who already uses WebRTC instead of rtmp to stream the live camera feed. You can use tokbox's apis for example.

Delivery: This is where it gets more tricky, the nice thing about http based streaming like HLS and DASH is that it's cacheable just like any other file served over http - making it extremely scalable and that's how most CDNs operate today. Changing that part into WebRTC has it's benefits like low latency but has a huge degradation in scaling complexity because of the connection state oriented nature of WebRTC, there are companies trying to build that as well e.g: Red5
