I recently put seats from an 08 convertible in my 01.0 coupe. I didn't come across anything that looked like it would prevent doing the opposite. One thing that could be an issue is if your car already has some kind of weight sensing system for the passenger seat. I'm not sure when those showed up. Depending on what year swapping from the airbag connectors stand a good chance of being different. I had planned on de-pinning and swapping the connector with my original seat but the wire terminals themselves weren't actually the same, so I ended up making an adapter that went beteeen the two. So if you get seats from a junk yard, take part of the car-side of the harness with the seat, just in case.

Here's thread I made about my swap you can check out
