... Obviously you've never seen a kid get upset over a lost toy being replaced with the exact same toy. Little kids can actually be MORE picky than we tend to be. My brother and I some how still managed to fight over our toys despite the fact that we both had most of the exact same figures. There were very few toys that I had but he didn't and vice versa. Most of the time my dad bought two of everything, one for me, and one for him. And we still ended up fighting despite being the exact same figure. If young kids can throw a fit over exactly identical replacements, then they're really not going to like that thing being used as a replacement for Galvatron's original head. The only way you can get away with a replacement head is if the kid doesn't realize that you bought a replacement. They have to think that is the original. You might be able to get away with it with older children. But they'd be close to the age where they're going to stop playing with toys and either loose interest or start becoming collectors. They'd still be young enough though that they probably won't know what Galvatron is suppose to look like. By that time then they'd probably just a head they think was suppose to go with that figure rather than the one it originally came with. Or if in a few years someone buys one from a yard sale not even realizing it has the wrong head, then they won't care. But being a brand new figure, people are going to know when they have the wrong head. It'll be a while before they stop caring about it.
