My wish list:
1) I would love to see them made a made for tv movie that dramatizes the production years of TOS, from Roddenberry's series pitch through the end of the original series. Spend a little bit of time showing "the filming of" but focus on the cast and producers outside of the studio.
2) Release all remaining deleted footage from Phase II and all the movies.
3) And all the wonderful ideas everyone else has come up too!
