I was thinking about Spock and Uhura having a kid again, and I still think that would be a neat element. I don't know if there is any media of Spock being a parent, like a comic or book but definitely not so far in live action. Spock being a dad and dealing himself with a kid with emotions just seems like such a logical story progression. Quinto and Saldana being parents could be fun. Would people accept kids on a TOS-era ship though? One of the things that I see a lot with ideas about if people could change TNG is throwing out the families and kids. Is there ever a point where families are okay on a ship? I think you could get away with two kids.
