I believe that you can request this modification. The outcome would be discretionary to the finder of fact based on yours. I would recommend seeking local legal advice and assistance with this.
Probably not. In the past some judges would allow this ans some would not. With the changes made to the cpo forms recently I doubt any judge would allow it. File a motion to terminate the cpo. I suggest hiring an attorney to help you do so because terminating a cpo is often not easy.
