If you wanted to have them all displayed, you would have to buy 5 figures at $30-35 a piece. It would also likely be quite a bit more than $30-35 for what you've suggested. Vykron came with 3 interchangeable armor sets. If a Skeletor or He-Man set had 5 or more sets of interchangeable armor, it'd probably be closer to $50. In the long run it would cost more and I don't really like the snap-on armor pieces that Vykron uses.
Mainly, I don't want to see this because I feel to many details would be compromised to create all the different looks with one buck.
