Question for anyone who knows their way around cocktails and liqueurs (Sheridan’s)

I’ve got a question for anyone who knows their way around cocktails and liqueurs. I recently finished a bottle of Sheridan’s (which I love maybe a little too much), and now I’ve got this cool dual-chamber bottle sitting empty. Since the bottle pours two things at once, I was wondering what other two drinks might work well in it.

The original Sheridan’s is a mix of dark coffee-chocolate liqueur with smooth vanilla cream, and the cream side pours a bit slower, so it balances out the flavors. I don’t need to recreate it exactly, but I’d like to try something that has the same kind of balance—two flavors that complement each other when poured together.

Does anyone have good recommendations for combinations that might work? Ideally, it would be something available in the U.S. since that’s where I am.

For reference, Sheridan’s has that nice mix of coffee-chocolate depth with a creamy vanilla smoothness. It’s not overly sweet or strong, which makes it perfect as an after-dinner drink, with coffee, or even just as a tasty shot.

Thanks in advance for any ideas!
