I would recommend it as something you could try.
I will try it, but it's not so easy as I inserted a tight-fitting 1" ally tube and that will be a lot of effort to remove. I have to remove it as it didn't go in very far before getting TOTALLY stuck. So if I just put in a dowel as is, it wouldn't stiffen up the crucial portion of the post.
