Seriously, contact your local service center. I'm sure it's possible, but there will undoubtedly be a charge. But the seats will no longer match the interior. It's going to look strange.
I was shopping inventory cars a couple weeks ago and was told that changing out seats was not a big deal (from textile to leather). I also asked about the dashboard pieces and was told those were much MUCH harder to swap. Seats didn't seem to be an issue at all.
