I don't remember ever reading about a gen dial swap for the SW. To be quite honest I don't see the need for such a swap. Of course It would be your watch to do whatever you wish. But these dials are very very good on there own. Now that It has the C1 super lume and thicker numbers...a.very good dial is even better. I could see a gen bezel change for some...but a gen dial? I would do some serious side by side comparisons before making up my mind. That's of course if you haven't done so as of yet.
If I was looking for a project or a watch to do mods on... this would not be the one. It's just to good out of the box to put the time effort and money Into. Again....just my opinion.
I would contact Josh @ PC or Andrew @ TT. Im sure they can answer your questions In regards to the mods. From what I can see the dial swap shouldn't be a problem. But I've heard that removing and Installing Breitling bezels can be quite difficult.
Good luck.
