Mike, I hope you are able to resolve this. I was browsing the internet and saw the letter requirement but thought that might be old info. Is the data you are looking at current? I also saw a lot of trucks for sale with that switch in them so it hopefully isn't too difficult to get done.
For anyone unfamiliar, the 2552 was created as an extended 2551 to resolve this same problem. However, the original mod was to put a fully anchored, auto seat style captain's chair behind the passenger seat so a baby or young child could be properly fastened in. Since most people don't need that, the subsequent 2552s came with the movable Euro chair which we personally love. While I'm sure you can get the captain's chair if you order it during the factory build, I don't know if you can have it added later. That's a question for Earl. And to swap back the other way would leave multiple holes and marks in the flooring.
Ron Ditmer has pics on the forum of his captain's chair in his 2350 which has the same space in that area. It is fully functional and swivels and reclines. It just can't be moved around the coach like the euro chair can.
