Yes, I think resetting a Hobbs meter is a great idea! Except that I used to work for a flight school and we would always catch anyone attempting such types of deception. Further that would classify as tampering with an aircraft which is a federal offense; additionally such actions could easily lead to felony grand theft charges, in addition to a few others. Times might be tough but certainly not worth ruining your life and career over. That said, You can do anything you want as long as you are willing to pay the price for it...
