I think she's probably as fine a choice as any, and it will be good to see her joining an interesting cast, which also now includes Canadian actor Bruce Greenwood in the role of Captain Christopher Pike, the first captain of the Enterprise. The character of Pike (played by the late Jeffrey Hunter) was introduced in the very first Trek pilot called "The Cage," footage of which was included in the two-part episode "The Menagerie" in the first season.
For a Trekker, this new movie looms large on the horizon and it will be exciting (if perhaps a bit sad, too) to have different actors and actresses portraying the characters we've known and love for over forty years. As I said, not exciting for non-Trek fans, but thrilling for the rest of us!
