Mustang Brakes?

Hey guys. Before anyone jumps on to me for cross breeding, here me out, lol. I was looking into brakes options for my dart, and my original plan was to reuse the back drums and buy new front drums,(I can't afford discs, and donor factory disc cars aren't in my area). I had an idea though: how hard would it be to use mustang front discs on my car? More specifically a foxbody. What do you guys think?
