I personally think the smoked cubes thing is kinda gimicky (and would be hard to pull off). Check these out, especially the bourbon ball coctail and the American. They use a lot of makers, but I'd substitute something else. The infusions might also add that flair that your boss might be looking for.
Bloody mary also sounds good.
This is also a great bloody- you can also add peppers/onions/garlic to vodka infusions or gin for bloody marys and that adds some pizazz.
