Any tips or experience doing this? I am looking for sources of good scion wood, especially for J. regia that will produce reliably in this more northern part of the range.
Did you ever succeed at this, Ray? I am going to try some this spring, but with scionwood from one of my own trees which has jumbo nuts. I have a lot of field volunteers to graft onto, and so far have about 20 pieces of scionwood in the fridge, but I have never grafted before. I have recently watched 20+ hours of YouTube about grafting.

Bark grafting, mostly but if I can get some good matches on wood diameter I will also try some whip grafting. I cut some scionwood last week, probably too soon, but I am over eager. I may try rooting them as cuttings instead, and wait a bit longer to cut more for scionwood.
Just noticed that it's J. regia that you're doing? I hadn't thought of trying to put that on J. nigra fieldstock. Hmm. Maybe we could trade some scionwood? I am starting my own J. nigra cultivar. I don't know all the characteristics, like flowering, etc., yet., but last fall the mother tree for my new cultivar - Juglans nigra 'Clair & Peggy' - produced nuts larger overall than any other J. nigra cultivar I can find data for. Its nuts averaged 28 grams when cured. It also slight beat-out or statistically tied, the leader in terms of amount of kernel, by gram per nut. Tastes good, too, and when cracked comes out easy in quarters
