Leyland Cypress edible companion plant?

I've got two sides of our backyard, NW-NE approx 4-500', lined with 30' Leyland Cypress. Zone 7a. I've been thinking about planting something next to them. Just not sure what. Thinking blueberries would appreciate the acidic soil from the years of pine litter. Any thoughts?

Anybody, should I repost under a different topic?

Yea, I saw that last week when you posted it, and I still don't have a suggestion. When I think of Leyland Cypress, I think of a screen plant that is just supposed to sit there and block the view. I guess blueberries might do well on the sunny side of them, but since I haven't tried that combination, I kept my mouth shut.

Tim, from my observations, this answer: underneath the Leyland only Chelidonium majus and Prunus domestica subsp. insititia 'Mirabelle' runners (I acquired it as a runner from a true species and it keeps on proliferating ) and they don't grow that well. Its mostly used as a wind shelter and/or ornamental hedge . Seldom seen mushrooms under them . Is a good biomass producer. It shelters birds, caterpillars and my cats.
Zone 6 , Belgium , this coordinate 51°19′N, 4°51′E .

I was wondering the same thing about planting blue berries next to Leyland Cypress.  Since this was posted 10 years ago, I am wondering if you tried it and if it worked out.
Thanks!
