Nice line up! I don't see any overlapping profiles with any of those choices; they all have a very distinct flavor profile. I never tried the FA Mellow Sunset, but I heard it's tasty.
It would behoove you to vape each one of those (5 or 15ml worth) as a stand alone mix before you start in on mixing with them. It will give you the opportunity to study each tobacco carefully and adjust your preferred percentage for those flavors.
I say that because, I ruined many a tobacco mix due to rushing that process.
