After the flywheel and damper drive modifications to increase clearance, I still only had 1.43" to squeeze it in there, so that is why I also shaved a little off of both sides of the rotor cup and also machined a shallow depression into the backside of the psru backplate to allow mounting the stator close to the plate and still have clearance for the windings. This link will show a pic of where I measured the 1.43" https://photos.app.goo.gl/K7MLLdvV6QwLYVG89 At a little over 1.5" before any modifications to increase that room, then you are much better off than I was when i began. When I decided to try it, I really had no more than the desire & determination to experiment and a "Hairy chested hero" idea that I set down $400 at the local Harley shop as a bet that I could make this work, knowing also that I was modifying an expensive PSRU, that is no longer available for purchase. That gamble paid off for me and I proved that it can be done. So I would say that you gotta ask yourself whether this is something that you really want in your own installation and if yes then put that money down on a single rotor/stator and go to work to see if you can make it work for yourself on your own design. Then if you are as happy with it as I am with mine, you can figure out at what cost you can offer it as an option. If I were in your shoes I don't think that I would go to the trouble if your only motivation is to provide it as an option for others. But if like I said, you want this for yourself as well, then go for it and if successful and affordable, then others can have the option of one as well.
