What If Wards Could Stack To Increase Their Range?

This is an interesting thought: What if control wards or trinket wards could be stacked by teammates to increase the ward's vision range and durability, perhaps by 1 point per stack? Each teammate could only stack 1 ward on each, and wards could be ranked from level 1-5, depending on the number of stacked wards on it.

Many times a team will have to place multiple wards near each other in order to secure vision in a crucial situation, and while this increases the durability of your vision but decreases its range, having one stacked ward down would increase vision range while slightly decreasing vision duration.

Maybe this has been thought of already. Still is a neat idea and could create even deeper vision strategies.
