Super Large Prints?

I have been thinking of setting up my darkroom to do super large prints at some future date. I would have to clear a space at one end of the room so that I could turn my 8x10 enlarge head side ways to project on a wall. I would need to figure out some kind of magnet system to hold the paper on the wall. It would be quite complicated to set up and do, the development would involve very large trays or a tank system a friend gave me. It might be fun to try especially with the 8x10 negs, possibly for the "Toot Yung Gallery" show in Bangkok, when and if that happens.

Here are some mural papers I found today:
