Can I chenge the icons used in Yast?

I’d like to change the default icon theme used by Yast if possible.

I use the beautiful La Capitaine icon theme for my desktop, that includes icons for the various Yast modules (I can see them in the menu or in krunner search results).

I’d like to use them also in the main Yast window, is it possible?

there was recently a thread on factory mailing list discusing icons, with tips how to change: https://lists.opensuse.org/opensuse-factory/2017-02/msg00186.html. if you get things working thanks to post result!
