This is the most viable way of micro transactions without messing with balancing issues. I suggested this a few posts back. If you want to have a mall that does not turn away certain gamers you should simply put in cosmetic changes. Some people might find them worthless but for most people looking awesome or differentiating themselves from the populace is worth a couple of bucks.
