I like the idea. I have a couple permanent ground brush blinds at my lease for deer and turkey hunting. I transplanted nearby native vines around the base of them to grow over the piles of limbs for a living brush blind. The only thing I would wonder about your project is will the vines you have retain the leaves once cut or after a freeze. If so, will the vines without leaves still be enough cover for what your wanting. The vines on my brush blinds drop all leaves at once in the fall, probably with the first freeze.
