Not only challenging, but expensive and heavy, especially when you factor in the hub and multiple blades. If you are looking at something like a Corsair, the prop arc on that airplane with the three-bladed prop was 13 feet. I don't have the numbers in front of me, but I am pretty sure the four-bladed prop was even bigger.
Depending on the area you live in, you could probably contact a local air museum and see if the have some that they have that are no longer usable. If not, they may know where to find one.
