Frankly, such a thing should be a Young Avengers/Champions crossover. Viv would have emotional stakes in any attempt to rebuild Vin. She's been rebuilt herself. Vision thought she was dead, after High Evolutionary turned her into a human and she then sacrificed herself to stop his plan in the Worlds Collide Avengers/Champions crossover. Vision made a new Viv from scratch. Viv 2.0 was evil. The original Viv managed to convert herself to data, and got home just as 2.0 was awakened. 2.0 then attacked the still human Viv but Viv killed 2.0 in self-defence. Then, with the help of Nadia Van Dyne, Viv downloaded herself into 2.0 (whose body was repairable, but mind was thought to be brain dead, destroying her human body. That's what you have in mind for Vin, right? He's brain dead, so Jonas, whose body was damaged beyond repair, would be downloaded into him?
