Is it possible to edit HUD panorama assets (such as the minimap or shop button?)

I want to move the minimap to the top right and turn it from a square into a circle. I have managed to do this where it works in hammer by adding and editing a styles/hud/hud_reborn.css file to my panorama folder, however in real dota (not tools) all the changes seem to revert to normal dota rules.

So is it possible to change these and if so where would I do so?
