Assuming StarFleet didn't intend on losing it's one and only Sentient & Sapient Android, would there have been a mission to time travel back and save DATA for the future? I'm making several assumptions, that StarFleet from the future (Post Nemesis) would value DATA / Soong Type Androids and use the technological genius in his engineering design for good in the future? Assuming StarFleet could time travel back to before DATA was destroyed, could they potentially transport DATA before the events of NEMESIS, scan him with the Transporter, and replicate him with an Industrial Replicator and scan him down to molecular levels to make a detailed schematic? They could of course return a clone of DATA programmed to do everything he was going to do in "ST: NEMESIS" and therefore not changing the timeline. We know that most replicators can't replicate biological tissue / living cells. That episode of ENT: "Dead Stop" where the Alien Space Station tried to kidnap Mayweather and use him as a Biological Computer and faked his death with a replicated Corpse with proper damage marks. According to Memory Alpha, most normal replicators can't create actual living matter. That being said, DATA isn't biological, he's completely Synthetic and Technological. Wouldn't it stand to reason that DATA would be easily replicatable and you can literally mass produce him with a detailed scan from the Transporter and use the Industrial Replicator to mass produce him? Imagine literally Millions of DATA like beings with Subspace connections to each other like the Borg Collective. The benefits of Mass Produced "Soong Type Androids".
