I'm not a music teacher, but I've had a thought.

Donuel, do you touch type? If you think of right-hand picking at typing, would that help? Think of the index finger as j, middle finger as k, ring finger as l. You could even write j k and l above the notes of a picking pattern and then type them.   

And maybe it's just a question of doing it more. Our hands connect to different sides of the brain, and it takes time to master any task where the hands have to work together. New nerve paths have to be established.
