I should get around to getting up Bimberi this winter, I've been meaning to for years but have never actually done it.
Gingera in the snow is definitely worth a walk - I've been up there a few times and it's very scenic. Next weekend is looking good for such a trip if you're considering it with a decent amount of snow predicted early in the week then fining up for the weekend. Note that you do need to have some degree of fitness though as Stockyard Spur is very steep coming up from Corin Dam and the snow makes things harder once you hit the snow line (snow shoes help if you have or can borrow a pair).
