I just did this for a vacation travelling bar (with 20 bottles), and reverse engineered it by drink like Rafa suggested. I generally only need to make drinks for myself, and live in a control state, so my list was a little different. If I had a gun to my head and can only do 10 (not counting vermouth or bitters):
Rittenhouse Rye
Cazadores Reposado Tequila
Vida Mezcal
Monkey Shoulder Scotch
Cardinal Gin
Fair Game Apple Brandy
Cynar
Maraschino
Fernet
Cointreau
Edit: Oh man, I didn't even get a rum in there, this is no way to live
