Glass and Mirrors - Removing mirrors from walls

I have several walls that are mirrored and would like to remove the mirrors. They have been on since the house was built in the late 80's. Am I kidding myself, or can they be easily removed?

Mirror removal
The quickest method I have found is too:
Lay down heavy drop cloths
Score around the perimeter of the mirror with a utility knife to minimize drywall paper damage.
Score the mirror with a glass cutter every 6 inches on the vertical
Run duct tape every 10 inches on the horizontal
Place a slotted screwdriver behind the score line at the top and gently tape with a hammer to run the glass.
tap the front to continue the score line and remove each piece as you can. Eventually you will need to use a wide chizzel bevel face down to remove some sections.
As carefully as you can remove the paper of the drywall with adhesive still attached.

or

Cover with a drop cloth that drapes to the ground and hammer for a few minutes...Then remove by section.....

With all said and done it takes about 15 minutes to clear the wall and 30 to clean it up........WEAR GLOVES

Skim coat, sand, prime and paint........1 hr plus......
