I agree that the best options for you would be the 2 above. Id do the brandy myself but if you dont want to change the flavor profile as much the Everclear would be a better option as it wont require as much with the much higher abv!
What about a blackberry brandy? I've never tasted one, so I could be way off, but wouldn't it be a good choice to help keep the flavor profile and add alcohol?
IMO not a good match. They are very fake tasting at least all the ones Ive had. Out of them though if I were going to use one Id go with the Poilsh Jesznowka (spelling ?)!
