Best of the Black Series?

Let’s say that in the future, Hasbro decided to revisit some older, in demand Black Series characters (like they’ve done recently with Darth Revan for example). How do you think they should go about it? Straight reissues or slight tweaks to preserve the extrinsic value of the first release(s)? Complete retooling/redecoing to improve upon existing sculpts? And what would you call this special line of Black Series figures –  Black Series Greatest Hits? Black Series Redux? Best of the Black Series?  Feel free to comment on the characters you’d like see again (or maybe for the first time) at retail.
