In general, I like the game mechanic of augmentation crystals, but not their physical description. I think the suggestion of having these be wraps or ribbons which could be applied to an item, or some other kind of fetish, is a good one, and seems more on par with a "move-equivalant" action to swap, especially if by their nature they can tie/loosen themselves on an item.
So, before throwing out the baby with the bathwater, decide if it's the interchangable crystals you have a problem with, or interchangable properties. If the former, you can always change the form to your liking. If the later... well, move along. Nothing to see here
Someone already pointed out the Guild Wars MMORPG method of doing it. There, wraps and "staff heads" are the ways it's done for spellcaster items. I could also see bowstrings which give a ranged weapon its particular property. However, swapping sword pommels and hilts would still not be that sensical of a mechanic IMHO, unless your world has Eli Whitney's Sword Factory.
Of course, in Guild Wars you can either place a new wrap on an item, destroying the old one, or try to salvage the old one first, with a 50% chance of destroying the entire item.
