Pawpaw and Hazelnut Hedgerow

Just sharing something I did recently and am proud of, while also looking for some advice or ideas.
Here's a video I made of a pawpaw and Hazelnut hedgerow I just planted at my house. Pawpaws are planted in a row (spaced about 10ft apart). And then hazelnuts are planted densely in a row that's about 5ft to the Northeast of the pawpaws.


Has anyone created an edible hedgerow like this before? Any suggestions of other plants (understory, vine, shrub,) that I could add to this system for diversity and more food?

Any suggestions on people's top 5-7 pawpaw varieties to graft onto these trees? I'd love a row of trees that produce a diversity of named pawpaws. Some to sell, some for seed saving, and a bunch for eating and freezing. And also just to have access to some cool named varieties and compare and contrast them.
Thanks!

Interesting idea. I have a “Shenandoah” pawpaw that has large, white-fleshed fruit with mild flavor.
