They both modulate GABA{A} subunit. Moreover they're from the same class of drugs. And even more they're both one of the most potent in the class as anxiolytics. Clonazepam doesn't do much if you're already addicted to this, subjectively of course, it's not a fun benzodiazepine, it's just as it is. I'd consult a doctor if I were you. This is not a good way to lower your Xanax intake.
