The only problem might be keeping the yeast from becoming inactive over a period of time. I don't think you could freeze them though because that might kill the yeast.
I did this before I started milling my own flour. I would make 6 or 8 portions of the dry ingredients (except the yeast - I think I added that when I baked the bread.) It was easy to do a bunch of mixes while I had all the ingredients out anyway. And then when it was time to bake, it was so simple!!
