While space IS a problem, I think a more serious problem is the fact that glamour is tied to gear, rather than to job. I don't WANT my DRK to have the same look as my PLD, or my MCH to look like my BRD.

Space issues are manageable, even now. The shared gear option, though, is not - not unless you're willing to undergear one of your jobs for the sake of having a different look...
