Given the ages of Peck and Wesley -- they currently portray characters significantly younger than they are -- I sometimes wonder if SNW wouldn't just "jump over" TOS entirely at some point to the TOS movie era.
I think what I'd do...
Pike hands over the Enterprise to Kirk, knowing that his time before Talos IV is short...
We have the accident that cripples Pike...
"The Menagerie" from Pike's POV...
And then Talos IV isn't the end of Pike's story like he believed. A movie-era "Search for Pike" -- there's been a medical breakthrough that can restore him, and Spock, Una, and Kirk return to Talos IV.
