This would be the way to go Will25. If you record on tracks 1~6, you can then bounce those 6 to 7 and 8. The benefit of this is that a) you can pan the instruments however you like across the stereo field and b) you have 6 free tracks again. You could repeat the process with new stuff (tracks 1~4 going to 5 and 6 as a stereo pair }.
But like Lt Bob says, you would need alot of experimenting and further to that, your stereo tracks are fixed forever and it's a headache and a nightmare. It's going to be almost impossible to know at the first bounce what any of the other bounces will sound like. There again, this is dependent on what instruments are actually being bounced and how many elements are in your song. For example, that first 6 track bounce could be drums. It can definitely work but it's not easy. Might be just what you need to get you well in there !
