As long your not using graphics from the skin I see nothing wrong with doing that.
I agree.
Funny how when the conclusion is the desired outcome how quickly we agree.
I'm afraid WG's explanation is a bit wishful. You've already stated your desired goal. Therefore, the onus would be on you to prove the graphics you used were yours.
HOWEVER, if you make the dock only for yourself, and do not publish it, no one can say or do anything about it.
