If your wife becomes a citizen, you can meet the RO by living with her outside Canada instead of living in Canada. You need at least 730 days in any 5 year period. You could let your PR card stay expired and come back to Canada after 10 or 20 years and renew it based on that you have spent at least 2 out of the previous 5 years accompanying your Canadian citizen spouse abroad. That is as long as they don't change the rules
