Switching Texture On Target Tracker

I want to create one target tracker, which has 2 targets. A live version of the art, and the 2D image provided by the artist themself. Is there a way that I can track the 2 targets at the same time with the same target tracker object. I could use multi-target tracking but, I would have to duplicate everything for the different target-tracker object which is going to mess with the size of the project.
