Bad idea. 15 hp is too big to transfer in rough water, but not big enough to get you out of trouble, on your 14000 lb Mainship. And that would be after spending time, effort and money trying to fab a satisfactory mount on your swimgrid and reinforce the SG adequately to hold a 15 in place.
Far better to keep the outboard on the dinghy and tie to the hip. 15 isn't enough to do much more than hold your boat off of the rocks, head to wind, should you run into trouble, so you should think about upsizing your tender to 25 or more hp. Then you can relax in the knowledge that you can actually move your boat where you need to, in rough conditions, should that emergency arise
I had to move my sailboat (8000 lb) when I lost a prop, and 15 on my dinghy, on the hip, was adequate. My next boat was also a sailboat, 16000 lb, so comparable to your MS, the 15 worked, tied at the hip, but that was in perfect weather, when I tried it. I wouldn't have trusted 15 hp to be enough in bad weather or a strong current.
Tying to the hip can be done in rough conditions. Lifting an outboard from the dinghy and transferring it to a SG mounted bracket can't.
