There are a few things I like about having Boyce on the show. One thing mentioned is we can have a older character to contrast what I assume will be a mostly young cast. The other thing is I like having someone who Pike can confide in which will be a big issue I think since Pike knows about his fate. What I would like is to see him have a small but important role during the first to maybe 2nd season and then you kill him off like say Mrs Landinham on West Wing. The one person he trusts most with is now gone creating a sense of isolation and being lonely having to keep those feelings inside. This eventually gives way to him creating a stronger bond both with Number One and especially with Spock. This is where we see how his bond with Spock becomes so strong that years later he will betray Kirk and steal the Enterprise just to help his old captain out.
As for who to play him I also like Combs but IMO the person I think most of would be John Slattery.
