I just played through this mission with an alt, and I like it. However, the Wolf 359 battle can be enhanced with having an Excelsior (Two at the battle: Roosevelt and Melbourne), Nebula (Bellerophon), an Ambassador (Yamaguchi), an Oberth (Bonestell), and there is already an Cheyenne in the background (the Ahwahnee) and a Galaxy (Unnamed so far).
Some non-on screen referenced ships:
Miranda-class Hoagland (from Shatner's The Return novel)
Ambassador-class Kadosca (from Super Nintendo DS9 Crossroads of Time)
Excelsior-class Righteous (from the Video Game Borg)
Excelsior-class Hood (from the TNG Comic Friends and Other Strangers)
Excelsior-class Potemkin (from the DS9 Comic Program 359)
