I suspect that disregarding TextFrames can be difficult because both the original Oberon System and V4 GUI are tightly integrated with TextFrames. 

System-3 Gadgets departed from the tiled screen layout in that they can "hover over" the desktop. If you really want to move towards the overlapping frames then System-3 is a better bet. An enormous work was put into System-2 over the years. Trying to implement a very simple version of it may not be the best solution because there are many issues which have to be taken care of. Studying System-3 may be very helpful to realize those.
