There are two factors that will drive the degree of difficulty of such a change:
The first is the width of your bike's rear triangle. If it's 130mm, that's good.
The second is what kind of shifters you have. If your shifters and brake levers are combined, that's bad.
If your rear triangle is 130mm and your touring bike has bar end shifters; you are a freehub body, cassette, and chain away from 9-speed. Figure $100.00 for parts. You'll need to do some rear wheel work, but that's easily done.
One factor you might want to think about is: "What's doing this going to buy you?". The answer is that your lowest and highest gears will be the same, you'll just have smaller steps between them. It's nice to have closely spaced gears but, performance wise it's not much of an upgrade.
