I think that is not going to work.

What we need here is a way to decouple the actual focus location (ie where
key events get sent)
from the focus indication (what to draw the focus rectangle around). With
gadgets, this was
separated by having focus location always be the widget, while the
rectangle could be drawing
around one of the gadgets inside.
