Would the ride be ok or would it upset the balance? Also I think it would be a quicker project than tearing up the transom and it would add a nice platform for swiming
What do you guys think?

It WILL upset the balance and tend to hurt the ride, but there are ways to compensate for that. (Search for my post on pros and cons of brackets) Here's what I'd recommend, based on my experience with a Seafari, which is less stern heavy than any of the cc models:
1. Use a bracket with biggest flotation tub you can find (a Hermco!) to maintain self bailing. Use the smallest setback you can live with. (Don can make 18, 24 and 30" versions.) I went with 30" model because I do a lot of diving, and it's great for that.
2. Use the lightest motor you can find that provides enough power for what you want to do. This eliminates all the 4-strokes except maybe the Zuke 140 and smaller. I ran mine for over 30 years with an old 300 lb 90 hp (at the prop) V-4 and it rode great. I run mostly offshore, and you can't run much over 20 kts in the 20' hull without going airborne if there is any sea running anyway. Don't run much faster with the 150, but I now have a lot of margin for heavy loads.
3. Plan on running a 4 blade prop to get more stern lift. Trim tabs and a doelfin or equivalent will also help. For some reason, maybe the 25" shaft or added leverage with the bracket, power trim is much more effective with current rig than it was with a 20" motor on transom, which will partially offset the rearward shift in CG. My original rig would plane at 12 mph, which is nice when it gets sloppy. Could not do that with new rig till I went to a 4B prop! Denny
