Can raycast or linecast hit a skinnedMeshFilter with no collider?

I have an object that I want to make transparent when 'blocking' the player's view of the character but my 'SeeThroughObjects' script only works on colliders. I tried "hit.renderer" but that didn't work. I can't attach a collider because the object is awkwardly rotated and scaled in blender such than no matter how much 'tinkering' I do(I've spend hours), I can't get a collider to even slightly line up with the renderer.

 

Can you make a parent object with a collider, then stick your awkward object in it as a child and set render/material properties recursively?
