I'm sorry, but I am unsure about which post you're referring to and what you mean by having enough time. Is there a time limit for you that day? I would not take along the luggage to Mörel, but ship it to Davos or Brig, wherever you need it first.
Winter clothing is not necessary, but you do need to bring multiple layers so that you can adapt when it gets windy for example. The temperature varies greatly; you can best check the weather forecast that morning to see what to bring. Still you need to be prepared for unexpected weather changes though.
