I agree about the reworking and ST 09 could have bridged that a bit. Largely because Nimoy was one of the best parts of that film. I always appreciated him in there.If the Star Trek reboot was to be something drastic, it probably should have taken a cue from Ron Moore's BSG. I don't mean in the sense of going dark and gritty, but rather that it's a total reworking of the original concept with no ties to any of the previous iterations of Trek. Honestly, I would have preferred that for a restart of Trek back in 2009. One of my least favorite aspects was dragging Leonard Nimoy along, as if the filmmakers weren't confident to do their reboot without having one of the old stars come and pass the torch.
I think that the Kelvin universe can provide that jumping off point to go different if they are willing to try.
