cherry trees and a lilac hedge

This is my idea of late.  We recently tore down our garage in hopes of creating a backyard, and our backyard still has its challenges, between our dogs keeping the mud muddy and the various empty beer cans, cigarette packs and God only know what else scattered as litter as the wind blows it to and fro.  Our backyard would possibly be a challenge to a green thumb, and our thumbs are not green.
At first I thought I would grow blueberry bushes as a hedge, and I was uber excited about having enough blueberries to supply our family and the apartments behind our house.  But there was this thing that I learned about growing blueberry bushes:  the soil needed to be quite acidic, with a PH around 4 or 5.  So I did a PH test of our soil that I learned over the internet which was, 1.  collect a sample of said soil in two cups.  2.  pour vinegar in one cup and baking soda mixed with water in another cup.  3.  If the vinegar cup bubbles you have alkeline soil, and if the baking soda cup bubbles you have acidic soil.  Eventually, the vinegar cup bubbled.  So scrap the blueberry hedge.
When I went to college, there was a lilac bush outside of the library and smelling that bush was one of the best smells ever for me, and the more I read about lilacs, the more I wanted a hedge.  So now my idea is to plant two cherry trees as "fenceposts" on the ends and then along the fence to plant four or five lilac bushes.
Will this idea work?  I do not know, especially because in our house we love love love BING cherries, although I am not a fan of the bing web browser.  So will our bing cherries and our tartanian mix well and grow well and get enough water and not get to cold?  Maybe you can tell me.
