I do always see the word "blog" as a wasted keyword. So in a sense, I do agree with your suggestion.
But the keyword you replace it with will need to be relevant and have a very broad meaning.
In your example above, the topics would always have to be about tourist visas. Which I assume would be quite restrictive, this approach is really attacking the small details - unless you're strictly writing about one topic, I'd just go with a generic term like /blog/, /news/ etc. I'd be more bothered about your internal linking to said page, use keyword-rich anchors opposed to just "blog".
