Is there a way to add a redraw callback to a live screen object, i.e. not via inheritance?

Reasoning:
I want to draw an overlay from an extension for widget sdk (substituting defunct position:absolute), so the screen is created by the bbwp stub.

I can get it by

Ui.getUiEngine().getActiveScreen()

and draw on it quite nicely, but I need a way to redraw when appropriate.

Note:
I've abandoned the approach to push the overlay as a screen, because i couldn't make it transparent / find a way to pass events through.
