I have read at http://e-liquid-recipes.com/flavor/25064 the Western (Cowboy) TPA have a Marlboro similar taste. So it could be a good start + Menthol. I have not try it yet.
You might like this, which only needs an adaptation to include a few menthol drops to your taste. http://e-liquid-recipes.com/recipe/750110 = Western, Burley, DNB .
I find about 5 drops of menthol per 10 ml is strong enough using Note Menthol which I found on Amazon (just over 50% natural menthol crystals in PG). Use whatever menthol you have on hand.
Red type blend is supposed to mimic marlboro red at 5-6%. Maybe smother some menthol on it could give you the result? Oh, and red type 2 actually have the menthol/mint added. Maybe you could go based on that?
