Don't care if Han and Leia are married, dating, UST-ing about, just want DadVader messing with Han. Make it AU enough that he's not a mass-murderer, but still scary as heck. DadVader is a total troll and he may claim he's doing it for Leia, but he's having way too much fun to stop, no matter how often or how his kids beg, demand, or scheme to keep him away from Han. Padme and/or Obi-Wan existence and/or appearances entirely optional.
Some ideas:
My, how long it took Leia to catch on, because Han doesn't like to admit things that put him in a less than ideal light... It does, of course, take Luke longer yet to figure it out.
Does Luke try to take father-son field trips to keep his dad away? Sure, no prob, Anakin's already booby-trapped the house.
Does Leia write increasingly long list of Things Dad Must Not Do? Sure, but Anakin's more creative than she gave him credit for.
Does Han try to connect with scaryDadVader? Oh, ho, ho, Anakin's sure hopes he'll try.
Does tiny Ben idolize his socially-a-jerk granddad? Why yes, yes he does. And okay, maybe Han was good for something, thinks GrandDadVader, but surely Leia doesn't still need him?
Modern AU DadVader trolling Han for his interest in Leia
