Thanks again everyone! It is great to have such a feedback.
Giles hit the nail right on the head with what he pictured. This is exactly what I have on my mind. Have the good old tent, stove and camping gear in the cases, some food, a bottle or two of fine red wine and a good book for the evenings, and off I go on some back roads for a couple of days, be it Hungary, or the countries and mountains nearby or (farther away

This is what I did on bicycle when I was younger and now I want to do the same on bike. I don't need a fast bike, I don't need a capable dirt bike as these are things which concern me not at the moment. I stay away from off road, but there will surely be some unpaved gravel roads with lots of potholes on my way.
Thanks also for one advice about riding in company. I can really be a maverick when it comes to getting away from it all, and those who I'd go with do not ride bikes. But I take heed and look for company. For all my other activities I always had mentors in some ways who could help me improving and this will be no exception.
One thing to clarify though, I'm looking for a GS, not a GSA. The latter is just too much for me I think at this stage. Also a lot rarer used here.
Probably it all just boils down to reason why to change from the Transalp
