Hi Schubert - I am really not very familiar with Musica Antiqua Köln. I don't believe the group is actually in existence any more, I think they disbanded several years ago. If I remember correctly, they are the ones who specialized in the lesser known composers of the 17th and 18th centuries, and when they did perform say Bach or Handel, it was lesser known works.
I have always had an interest in the natural horn, but I never did pull the trigger on buying one and really learning the technique, I have only just messed around on one for a few minutes in a horn shop before. There is an active early music group in my area who tried to talk me into it, and would still probably hire me and program some stuff with horn were I to decide to do it, as there is only one guy in the area who does, and he doesn't do it very well anymore (he is nearing retirement), but I haven't yet. It is quite a bit different from what I normally do, so it would involve much time and work in my off-season, when I normally take some rest from playing. Not to mention the money involved in buying one and traveling to take some lessons to learn the special hand techniques involved. I would be lucky at this point to ever break even on that, as there wouldn't be a whole lot of opportunities to perform with it, there being only the one group in my area. So I would just be doing it for fun, which it no doubt would be.
