I would suggest, not to because it includes a lot of travelling and the cold makes it even more difficult. To enjoy these beautiful places, a little more stay is required.
Also gurudongmar lake opens and closes according to the weather so if you are there for sometime more, you get sure for it.
You will be exhausted & not be able to enjoy any place. Gurudongmar lake takes one complete day. better stick to one for a day and enjoy it. Happy touring..
