I think you should move forward and make your characters as perfect as you can. Sacrificing better joints for backwards compatibility with old clothes might be good for PR in the short term. But in the long run, it'll hurt you. Soon, people will forget the favor of backwards compatibility, but they will continue to bitch about the joints for as long as the problem exists. You're going to have to do it sooner or later, so it's best to get it over with as soon as you can. Some will bitch, but most people understand and want progress. Another point: as it is, you have to fix the joints in postwork. So, with new joints, you'll have to fix the clothes in postwork. The advantage with new joints is you're moving forward and new clothes will be around soon enough.
