Paint "am i making a big mistake"
You already know what you're in for with a candy. I work in a paint store and try to steer people away from the candy's, just for the repairability. Alot of the new cars are tri-coats from the factory. With some looking you should be able to find a base/clear that looks very close to a candy. One that comesto mind is Merlot Pearl on a Nissan. As far as the stripe how about "ghosting" it on????? Adding black to the color or just a pearl midcoat???? Then bury it with clear........
