Collision detection using shaders?

Or shader collision. Runtime collision detection between shaders marked with collision flags. This is possible in Unreal 4?
It is only an idea I had when I was trying to create the collision for a spline tube to be able to walk inside it.

If I’m out of the loop and this is already implemented in Unreal Engine 4 or is there any technical limitation, then skip

Thanks
