That arbor-looking thing? It will be far from ideal, but with constant maintenance and training you might get something useful out of the effort.
Hops plants seem to spend a lot of effort to reach the sun. My second year plants averaged 30' in length (~25' up and then trained along the drop-suspension line 'til harvest). They likely won't be as happy when they run out of "climb" in - what - 5 feet?
