The ESB version of Yoda can not swap heads out with PT version Yoda. PT Yoda's hands and feet are not the same as ESB Yoda's. Same goes for the wardrobe. To much creative license occurred with the from scratch created CGI version of PT Yoda.
As for accessories. You have the bunsen burner styled lamp he holds, the box he was rummaging through to find that lamp, the lantern that was resting on top of that storage box, the fish tackle like box he was digging through for food, a log or tree base for him to sit or perch on, the blue backpack Luke carried him in, a cooking kettle, a wooden bowl, a wooden spoon, a boa snake, a lizard, his cane and his flute. A big accessory could be a 1/6th version of his hut.
Very excited to see what this fig looks like. The head shape in the teaser looks about right to me. The image cuts off before the top tips of his ears would be visible. I hope they figured out way to distress his robe to make it look tattered like it did in the film. It looks like they brushed the original raw india silk robe to cause random knots and lumps in the film.
