We'll also bevel back the inside of the transom all the way to the bottom of the well and along the sides of the well and tab the part into that structure also.

That sounds like a good approach. As long as your bevel is at least a 12:1 ratio to your laminate thickness, and 6" should be plenty, your seam should be very strong. I would use epoxy resin for the tabbing for its superior secondary bond, but some guys here might consider that overkill.

We use epoxy for everything except where it is prohibited by class rules. Its not overkill in my book, just better boatbuilding!
