What do you think of this idea for a short hedge?

Get some T-Posts, drive them down to about 3-4' high. Then run 2 or three strands of wire. Think of making a short barbed ware fence but not barbed. Then planting confederate jasmine (or something similar) along it and train it to grow on the wire. Do you think this will eventually become thick enough to trim with hedge clippers to make a nice solid 'hedge'. If not, is there something I could change? I have about 500' and that's a shite load of dollars in something like cherry laurel which I was thinking of doing initially.
