Defintely if you have a fruitcake that's too dry you should take some cheesecloth, soak it in whiskey, bourbon, rum, whatever and wrap the fruitcake in it. It'll moisten and flavor it. I make homemade fruitcakes every year and have people begging for them. I soak the fruit in bourbon (Maker's Mark) for 3 days before using it in the cake. I also use regular dried fruit not that crazy candied gunk that commerical people use. It has cherries, cranberries, pineapple, apricots, 3 types of raisins and currants. It's heavy but more like poundcake heavy not the dark stuff they us in regular fruitcake.
Made a Bacardi Rum Cake recently. Really loaded it up with rum. Everyone in the house had a piece and then my dog ate the whole rest of the cake, almost a half because it was on the counter. She wobbled around for about a half hour and slept hard the rest of the night. I'm almost sure she had a hangover the next day. It was cute but I was up all night worried about her.
