Two-way pistons (Java)

This idea is designed to work with my other idea, 1-way motion blocks.

The two-way piston would be like a normal piston, but slightly different. Both ends would push to make the piston two blocks wide, allowing for better flying machines. The piston could move both ways without braking or using slime blocks to pull the piston. If this is hard to imagine, think of a piston block with two moving parts that each move half as far. The piston could move both ways, but it moves the way that does not break any blocks. Thanks for considering!
