A missed opportunity
Doohan’s ashes to be launched into space along with fan tributes.

I don’t know. Seems to me they should expend every available resource to figure out some way to beam Scotty’s ashes to space. Anything less than ‘givin it all they got’ would be inappropriate. Once the technicalities are overcome, they can get Captain James T. Kirk to flip open his communicator and say, for the first and last time, “Beam Up Scotty”.
If nothing else, they should make up an elaborate hoax. The people interested in this kind of stuff would most likely buy it.
