“I do not believe that a “tolerance wall” meets the minimal standards for an Eagle Scout Project.”
You are correct. Was the proposed Eagle Scout Project basically a giant poster? As the proud mom of an Eagle Scout, I know that a giant poster or even a large mural does not meet the requirements for Eagle Scout. Not even close. There are very specific requirements for an Eagle Scout project.

I think post #61 describes the Eagle Project very well.
