Definitely a missed opportunity for a fresh new take on that character. But while her tics and mannerisms are similar to Gregory's, the underlying motivation behind her choices and actions are different. Where Gregory would take huge, seemingly random risks (Sesame seeds, ostrich farms, etc.), she seems to be much more analytic and logical, almost like an autistic Spock.
Otherwise, I love this show so much. The slow roll on describing Gregory's death "... A hippo wandered into camp..." and the negging of the the neggers during the funding pitches was just so brilliant.
