Concept: Vader is spawning. No one else knows how or why. Sidius calls him up one day and there's just. An Offspring with him. A Vaderlet, if you will. Asking "what the kriff is that and where did it come from" goes nowhere, and Sidius just accepts it for some reason. Vader continues spawning. Tarkin gets used to all the Offspring hanging around (if Vader isn't actively spawning he has one with him. Sometimes two or three). The grown ones merge into the empire maybe? Obi Wan shows up on the Death Star and Vader fights him with a child on his hip. This never gets explained to Obi Wan. Luke has three dozen Vaderlet siblings, and no idea what to do about it. They're the spitting image of their momdad, it's very disconcerting for everyone else.
I think Obi-Wan deserves to spot the Anakin clone and have a breakdown on the spot, right in the middle of the Death Star, because he REMEMBERS Anakin as a NINE-YEAR-OLD who needed HELP FIGURING OUT THE SHOWER and USING THE WEIRD PENS and--
"Kenobi. What are you doing?"
"YOU USED TO BE SO SMA-A-A-ALL."
Obi-Wan doesn't have to die for the young'uns to escape, he's too busy confusing and exasperating Vader with the power of nostalgic drama.
