this is not possible at the moment.
maybe this would help in the future: https://github.com/webcomponents/polyfills/tree/master/packages/scoped-custom-element-registry

If you'd like to replace a registered component, you could register a proxy wich then later could replace the implementation.

This is a spec question. It's currently impossible to unregister an element (and there are questions about what that would mean). You can see the spec issue here: WICG/webcomponents#754
