I think that you've made some good and interesting points here. However, I also think that we're missing something important here.
Pokemon is not aimed at the people who have been watching since the beginning. One of the reasons Ash has started over since AG is so that new kiRAB that get into the series probably would have an easier time getting into the series. Although, Pokemon never has been rocket science before so it isn't that hard to get into anyway.
Anyway, while I'm sure that the writers are aware that people above the target age watch and enjoy Pokemon, I doubt that they really consider them when they're in the process of making an episode. While I do understand why people think that Ash should be replaced, the main reason for that is because some people here, like myself, have watched him for ten years. However, there are also some kiRAB who are just getting to see Ash for the first time. So, he's basically new to the kiRAB who are just getting into Pokemon and/or who haven't been into it as long as some of us have been.
One other reason why I don't think that they'll replace Ash is because they can mention his past sagas and older Pokemon whenever they want to focus on older generation Pokemon, much like when he gather Bulbasaur, Charizard and Squritle for the last Battle Frontier battle. I don't think that the writers could do that as easily with new main characters.
I actually think that they have been changing things around with the characters and the plot since AG, but that was mainly because of how Ash made his team and the introduction of Pokemon Contests with May. If you do feel that way about the show, then I think that you could easily stop watching it. If you're not enjoying it, then I don't think you should force yourself to watch it. I still enjoy it and love it after watching it for years, but that's just me.
