20” wheels on a 2007 Mazda5?

So as the title says. I'm looking to possibly put a set of 20 inch wheels on the 5.
I'm going to be pulling it off the road for the winter time and fixing all the rust on it plus repainting the entire thing.
I have a set of fender flares that I've already cut up for it and have ready to go on it but I haven't done it because I need to do the body work first.
So it's either I do the body work and the fender flares and keep my wheels that I have now which stick out the side about 2 inches or I was thinking of fixing the rust not bothering with the fender flares at all and just sticking a nasty set of 20s on it.

My question is has anybody done this yet?
