Although it seems to me it would make a lot more sense just to go back to the prime universe, where Pike was captain of the Enterprise for years and Spock served with him.
Why are people so intent on returning to the old timeline ? We've been there for 40 years. Can't we move on, now ?
The OP asked about a series starring Greenwood Pike.
And I frankly don't see how that would work - and neither did you - given that he was captain of the Enterprise for 10 minutes, and his fate in the reboot timeline. I can see how it would work in the prime universe, however.
Not that I have any interest in seeing it. Greenwood did fine with the role, but his Pike's function was as Kirk's mentor, and now that's done. Plus, I think the lead in any new series should be younger than pushing 60.
