It wouldn't be difficult, at least.  The more hairy aspect is that you
probably want to create new subframes below/right or above/left of
existing ones.  I modified windows.c appropriately to do this for what I
call "window combos".  In your parlance these are subframes consisting
of a left and right (or upper and lower) window only.
