idea for a new type of gear

[Phantom59]

i was thinking it would be good if LG could combine 6093977: Double Conical Wheel Z20 1M  http://brickset.com/parts/6093977  and 4540381: Technic Coupling, Tight  http://brickset.com/parts/4540381 into one gear

Or you can just call it 20z clutch gear. Which certainly help when the model is dense and tight. The problem with 24z gears is that they need more than 3L around them to spin.
