As I recall it the Nunnery, like the other structures at Chichen, had very rough surfaces in its interior spaces. I guess that you might find carvings or bas reliefs there, but honestly, I don't remember any murals or any interior surface finished enough to be suitable for a mural.

I will dig through my photos tomorrow and see if I can find some of the interior.
