As long as they don't make him Skippy, the toothless Sanitation Engineer and station crank/drunk. Every once in a while one of them will say: "Gee, I'd hate to be like Skippy, living in the past.."
Hopefully, it will be something sufficiently meaty (and ego-boosting) like a leader of some of the smaller ships who have allied togtether politically and use him on screen for their spokesman from time to time or a former pilot training the new generation or something a bit more impressive than Skippy. What I am hoping he is not going to be (other than Skippy) is the "Other Officer", you know, that guy on the TOS (and quite a few other Trek and non-Trek programs) who is a pain-in-the-butt officer that comes sweeping in and is either (a) dangerously unstable or (b) hopelessly incompetent; thus forcing our stalwart heroes to either accomodate or circumvent him.
