Very good idea, though you would have to do some modifications to the tech tree so that it didn't max out before you even left your home quadrant.

I am not sure but I think I heard about something similar already having been done. I remember seeing a post about someone making a "hyperspace" map that was layered under the regular one some how. Everytime you would go through a warp point you would go to the hyperspace map and have to travel to the other end of the warp point (or something like that). I never saw the map itself but if it was possible then you might be able to use a similar method to layer a quadrant under/over another, connected by a limited number of warp points. Maybe.
