What I did when we were at 80 bpm, I cloned the 6 string and panned each at 45. Then I had a 12 string right down the middle. I'm not sure if that is how it will end up, but so far I like it. I should mention we sped up to 90 bpm, re-recorded everything, and it's sounding real good.
It seemed to me that without the 12 string down the middle, the rhythm guitars had no focus. I had the 12 string vol down a touch lower , and I really like the results. I sometimes worry tho, that I may be overproducing a bit?
My version of layered synths...
