Is it possible to collide with trail of trail renderer

I have an object with a trail renderer. I want to detect a collision of this object with the trail of it's own trail renderer? Is this possible? My first thought was to drop a collider prefab every n seconds at the position of the object with the trail renderer and then detect collisions with the prefab.

Thanks for any input you can provide.

 

There's nothing equivalent to a "trail collider", so dropping objects at regular intervals is a pretty good way to go. Performance may become a problem if the number of objects can get very large, though.

 

My thought was to drop empty game objects with a sphere collider.
