Morning,
I do not believe that transplanting at this stage is desirable unless it's an emergency. However I think a good session of defoliation could be good, roughly between 10-20% of the leaves to really open up the budsites to light and airflow. Also your cleaning of the bottom, I would agree about doing a bit more, the leaves you see that are only 3+ fingered small leaves, I would clear all of those away. By the look of the pic it seems theres a small cluster of them still sapping energy down there close to the bottom.
Best of luck on their finish, they look very bushy and strong.
