As far as HTC goes, no they don't have a complete pack. There may be some players out there that have the complete pack in a zip file or something. All of the skin downloading happens while you are in the game (provided you are past your two week free trial) let's assume you are past your two week free trial, in the hangar there is a checkbox to automatically download skins.
As I said, it's possible some AH player(s) have a complete pack. But from HTC's view, it's either download independently or let the game automatically download them while you play.
