Yes they do have different teams working on different aspects and systems of the game. And that's the thing, a Character Re-design option for 2.0 and one for this current version are not the same thing at all. While there is undoubtedly a team working on all things character creation for 2.0, you can be certain there is no one working on new character design options for the current version. Why would they be? Spend time, resources and money to appease a handful of people who absolutely cannot wait for 2.0 to be released in a few months ? Not likely.
And yes, it would hinder the progress they are making on 2.0 because they would likely have to pull someone off of something more important to create a feature that really isn't needed. Also, I am sure their response (whether true or not) would be that it isn't possible or it is overly difficult to implement with the current version.
I will say that I understand where you are coming from. I am personally happy with the appearance of my character, and have no plans to change it. But that is also why I understand how important it is to be happy with character, it is an extension of you after all. And you spend your entire gaming experience staring at it. But regardless of that, I don't think the Dev Team needs to be wasting time on this.
If its that bad just re-roll, or wait it out like everyone else.
