Resizing frames in combat
 

I'm trying to resize an oUF unit frame in combat so that I can show/hide some dynamic resources, but I'm getting a bunch of:

Is there any solution for resizing a frame in combat?

Resizing, hiding/showing or moving secure frames should all be impossible during combat (outside of the constraints of the secure system) because allowing arbitrary movement would open the door to "one-hit-wonder" type addons again.

Overlay a bunch of actionbuttons and take turns shrinking them to 1 pixel, or moving them outside the screen, or changing their strata etc.. you get the idea.
