William,

I cannot answer for Dan, but from my own perspective a lot of the movement you described is going to get re-worked. You just don't half-step tenkan in the same way (by moving hips) at least initially.

But your training passion will certainly prepare you for the hard work of making big changes to train smarter. Also, some of the time you had put in to other MMA will probably need to take a back seat for small window while you change over a bit, and then I would say you'll be able to get more bang for your buck when you do ground fighting or other types of MMA skills that may interest you.

In my opinion, the main thing to prepare for new body movements is getting rid of tightness as much as possible. Do yoga, get some deep tissue massages, do some fasting, whatever it takes so that when you learn new things with your body it's not any more difficult than it has to be.
