Have you tried just using Knob Creek Maple-Bacon bourbon?

Here's what we do in our home bar:
60ml Knob Creek Maple Bacon Bourbon
10-20 ml (adjust to taste) Grand Marnier Cuvee Louis Alexander
2 dashes Ango

Hope you enjoy

Very correct on Knob Creek Maple-bacon bourbon (one of our house fav's)
60ml KC MB Bourbon
15-20 ml (adjust to taste) Grand Marnier Cuvee Louis Alexander
2 dashes Ango

Shake, strain, & go...
... and you will be very happy.

UPDATE:
After trying this at the JFK Capital One Lounge, I asked how they made it.... Oh what an improvement! So, taking their recipe and

15 ml Elyx Vodka
25ml Midori
30 ml Grand Marnier Cuvee Louis Alexander
20ml Volcano Lemon juice
2 dashes cucumber bitters

First, thank you Simon for an amazing cocktail.

I made this slightly differently with the same proportions.

Soto Junmai Diaginjo sake
Either Purity 34 or Botanist Islam Dry Gin
Absolut Elyx
Soho Lychee liqueur

Amazing!
