In the school where I train we have a comprehensive test at 3rd brown which includes being able to do all the techniques up to and including the 3rd brown list right and left handed. The way I found that worked best for me (someone else already mentioned it) is to just pick one or two moves at a time and then do them with the other side. Another way that I've seen it done is to use the "mirror concept" some of you mentioned in connection with teaching kids (I do this too btw), have a training partner do the technique "right-handed" and you face them and mirror it. by doing the tech.'s slowly at first and taking turns with your partner you can pick them up pretty quickly.
