Except for binarity of planets, I don't thing sky renderings would be particularly cool. If we have habitable zone of 50 millions kilometers wide - just a rough number - then planet ring to planet ring distance would be 6 million kilometers, 20 times Earth-Moon distance. With 52 planets along the single orbit and orbital radius 150 millions kilometers (~billion kilometers circumference) the distance between planets on the same ring would be 20 millions kilometers. So I don't think planets would appear too big on the sky. What I'm not sure about is how we'd deal with sea tides caused by binary planets. Even Moon causes significant tides; an Earth-sized planet would have to be much farther away than the Moon so it woudn't cause ever bigger tides...
