Yes, yes, yes!!!
I would love to see Walt as an AA in One Man's Dream. In fact, my idea was exactly what CreamBunni already posted. It would make it more realistic and entertaining for my children, I believe. I would like them to be more interested in this show becuase Walt is such a powerful hero figure and I'd like my sons to know you can do anything you want if you work at it.
I think CoP would be another great location, as JsWalker already mentioned. I would like to hear a bit of the history of the ride. There are a lot of folks out there that don't know the historical significance of this ride and probably pass it up on the way to other, more eventful things. But it would be great to have an introduction with an AA Walt and maybe a Tiki Bird explaining how important AAs were and still are and the history of the CoP show.
