Regarding your question of getting 2 packs with profoto....I feel pretty strongly (however some would disagree) that each light deserves it's own ranger pack. While you can certainly plug two into one pack, the short cable length will deter creative placement and adding an extension cable is both expensive (more than $200) and will eat up some of the output from the head on the extension cable. If you can swing it, 2 ranger packs, 2 lights.
In a similar vein, I've bought a Quadra set, and I'll match a Ranger to it in a few months. Best of both worlds?
