There's no conflict. I didn't even send an explanation, just sent my passport (maiden name) and other information (married name) and included our marriage certificate. However, your COPR and PR card will only be issued in the name that appears on your official travel document (passport). I have the same issue, that I changed most of my info in the US, but because of the timing of when we got married, when we traveled to Canada to look for a house, and when we moved, I never had enough time to safely send off my passport for the name change. I am a PR under my maiden name. After some travel we have booked for March, I'll start the large pain-in-the-butt process of first sending off my passport to be changed, then requesting a new PR card in the correct name, and then trying to get my named changed on my SIN, etc. I wish like crazy I could go back in time and change the passport before applying. :-/ Especially because I live in Québec, where it's a fight to get them to recognize my legal name anyhow.
