How come I always need mirrors?

So, I figured out what it is that I want to do for the Table Top Show!
I'm going to place a mirror angled under the camera. The first shot will be of where ever the mirror 1 is pointed. Next, someone holding mirror2 will enter the picture holding mirror2 directly back at mirror1, they will slowly adjust mirror2 until the next person holding mirror3 enters the shot, the second person will then adjust mirror3 until you see the next person, I will continue this to the halfway time marker, the last person at that time will angle back to the person before them and that person will follow suit until it gets back to mirror1 under the camera. I thought of this in a dream, which usually means it won't work.
Early predictions:
I won't find enough mirrors
The angles won't work
The mirror under the camera will have to be huge (I really don't want to remove my closet door)
The images in the mirrors will get smaller and smaller
To make it work properly I would have to zoom each time a mirror is entered(which we can't do)
The mirrors will be too small
Natural hand movement will make it impossible to determine what's in the shot

I've thought of other ideas, but I really really want to shoot this...I will definitely have to practice this...
How come I always need mirrors?

Where am I gonna find these mirrors...I wonder if they have some in some in a drawing class... there has to be... a self portrait class? Or something.
