Here's a quickly thought of way aroung your problem.  Why don't you
modify things so that each "window manager" creates and operates within
its own draw-thru, sub-window of the root window?  For example, the room
manager would set up its passive-grab relative to the root window, and
the window manager would set up its passive-grab relative to its
sub-window of the root window.  Then you need to have the window manager
map all "top-level" window as sub windows of the wm's sub-window.  I
don't know if uwm normally does the remapping, but you could always look
in the "wm" code to find out how to do it.
