You can carefully watch your TfB durations so that you get two overpowers back-to-back while NOT delaying MS. I know that this doesn't directly answer your question, but it will allow you to spend less time in Battle Stance and more time in Berserker Stance (where we want to be).
I use Inline Aura (addon) to track how long I have on my TfB procs, and when I see it at 4sec remaining, I hit my Overpower macro to switch to Battle Stance, and then during the GCD incurred after hitting that overpower, TfB procs again, so as soon as the GCD is up from the first Overpower, I have the ability to use it again, and then during the GCD incurred during the second Overpower, I hit my Mortal Strike macro to take me back into Zerker Stance and hit Mortal Strike as it's coming off CD.
No, this may not net you more Overpowers, but your overall damage will be higher since you'll be spending less time in Battle Stance. I suggest practicing this on a target dummy before using it in a raid.
TL;DR I explain the double-overpower method, while admitting that I don't know how to get "more overpowers" while delaying MS. Also, it should be known that delaying MS is almost always a bad idea!
