Have you done Genoa Peak Trail? It start on the tahoe side off of Kingsbury Grade, you cross 50, then keep going on the other side and it drops you on the nevada side of the mountains. It helps to have a gps of a good map though, the trail network up there is kinda crazy.
Super easy, probably still really easy with the snow. Its basically fire road, but you get great views. After your cross 50 though it gets harder. I haven't done it after 50, it was on my list of trails to hit this summer but 3 rubicon trips took up a lot of time
