I use exactly the same tuning in my cover band! I've had pretty good results using 45 65 85 105, but with stainless steel hexagonal cored strings so they feel stiffer. Brands that I know of that use hex cores are D'Addario, Elites, and Elixirs.
EDIT: Oh, and I just remembered Newtone Strings! They use hex cores too, and you can ask them to custom make you a set if you do want to go heavier than a .110
