Have Any Of You Done This?

I have been struggling with an issue for a while and I think I have the solution. I cant really afford to get a set of wheels and new tires right now, but I want to go to the same width front and rear.

I am thinking of getting a set of wheels (7" wide) and two new rear Bighorns (29/11-14). That way I will have the same width tires and wheels for now and I can research more on the next tires to go to, after the bighorns wear out.

Have you or anyone you know run the stock rears all the way around? Pictures are worth a thousand words!
