What this sounds like is commonly called "article spinning". I appreciate that you want to do this manually rather than using software, but it's still not really a value add.
I also think that the Google spotlight is on this practice, as it is on all approaches for inflating content only to rank better. That said, it is a technical trick that works for some people, for the moment. I personally stay away from it.
