Use components from lovelace UI outside of lovelace UI

[jogibear9988]

Is it possible to use some of the lovelace webcomponents (like ha-control-slider, light-color-rgb-picker, ...) outside of the lovelace ui?
I'm working on a designer: https://node-projects.github.io/web-component-designer-demo/index.html wich works with webcomponents., and I'm thinking of includeing this to homeassistent, but I'd also like to have a library of nice looking UI widgets wich could be used to design the ui then.

At the moment I found no way of importing the widgets from a delivered Lovelace UI. Or is there a npm package wich I could use?
