there are no varla stones in Skyrim (lore wise they shouldent be any way). Its not like we need them, since the main method of refiling enchantment is more soul gems after all, but they sure were nice.... but hold on a second.
Dragon Souls (often implied to be stronger then most) are aperintly in abundance, and Soul Trap magic should bind that soul into a soul gem, perhaps one that could both make some more powerful then averge enchantments or even refill all your gears enchantments, as a more accessible and more economic way of dealing with the no-regeneration system. Of corse, these souls would probably need a grand soul gem (or even Azura's Star) to harness them, but that only adds to balancing them out.
Any thoughts?
