If you have the money, go for it if you have the space. The Aurora isn't a super heavy tourer, is it? I'd think you'd ride on it just fine unloaded. Sure, it's not a carbon race bike but obviously that's not a concern. A road bike loaded for touring can work but not very well. It would be a bit surprising if your road bike has chain stays long enough for decent panniers. If it does and you're entirely comfy on it then it will probably be OK if it can take tires wide enough for your intended use. My recommendation would be 32c for a basic minimum touring width. If I had a road bike I wanted to use for touring that's what I'd want as a minimum. In your case you are new to touring and maybe you'll like it and maybe not so it won't hurt to do some touring before you buy a new/used bike. Keep in mind though, your experience touring with a lightweight road bike will be quite different than what you could do with a full touring bike. You might enjoy one and not the other
