I can easily get you a Dream Ball Mawile and Murkrow if you are interested in those (and probably a few others that aren't on your list, but I'd have to look), but if you're only trading for other rare balls, I'd have to check and see what I want/am interested in (basically, it would mostly be other Dream Balls as long as they have hidden abilities). If you will trade non-rare-ball mons for these, I'd be interested in getting hold of a Diancie or Pokeball pattern Vivillon.
I can also work on getting you some of the English Kalos-born Pokemon that you noted that you want. Good IVs shouldn't be too much of a problem, either -- just a bit time-consuming.
