Cloning tracks will only give you the SAME gtr in the SAME amp. What works for me and the gtr albums I listen to is this formula. To achieve that Wall Of Sound gtr sound you hear on Queen, Def Leppard, or any of the metal bands out there is really a combination of DIFFERENT gtrs thru DIFFERENT amps. Try laying the first track with your primary sound. Then overdub from there with different amps or sims with different cabs and different pedals and preferably different guitars and different mics. Pay close attention to the mix and panning of the tracks. Hard left for a couple and hard right for a couple. Mix them up! Don't put all your dirt tracks on one side and all your slightly overdriven tracks on the other. Mix and match until you get a good blend for both sides. I prefer to assign all those tracks minus the solos to a GTR WALL BUSS. That way when you get your mix sounding right, you can turn all those tracks up and down with the buss volume.
BEWARE! You want to cut these tracks with no chorusing, delay, or reverbs. Chorusing is usually not used at all because you achieve that sound by mixing all of these basic tracks already. I prefer dry as possible and add reverb at the buss. Nothing sounds worse than 4-10 gtr tracks that sound like they were recorded in completely different rooms! It sounds much more authentic to add a nice room reverb on the buss!
Again, this advice is aimed at getting those power chord sounds. Solos are a little different.
I hope this helps you and is not too confusing. It is a little more trouble and takes a little more time but it is well worth the extra effort. I promise you.
