I'm inclined to say no, you're not copletely safe. As a rule of thumb, it takes about 5 elimination half lives to completely eliminate a drug. Clonzaepam's half life is around 30-40 hours in most people, so you'll probably be redosing just before you completely eliminate the clonazepam.
I actually doubt that you'll experience withdrawal at that frequency, and if you do, it will probably be mild. I don't think you would get much more than rebound anxiety and insomnia if anything. That said, I definitely wouldn't say you're completely safe from it.
