Super strong decent tasting everclear shot mix??

I have been drinking everclear streight, it's gotten old, I am trying to come up with a recipe that keeps the everclear super strong, but helps make it a bit more drinkable, i drink out of a flask for ease, so if you know anything that can keep the alcohol % up high thats best. I was told pure cool aid powders with a tiny bit of water and almost all alcohol, like 10X as much powder as would be required fro the amount.
