Gary, I don't know if this would apply to your situation, but have you seen those "iron on" strips of thin wood trim for plywood edges? You can buy the thin wood with or without adhesive already on them. Just glue it to the edge, let it dry, then really easy to file, sand,or otherwise trim the thin edge flush. If that would work, it would require the fewest tools and skilled labor...
I am impressed with the workmanship on those rounded edge additions in the pics. John
