People would love it. Even people who might not even recall the episode would enjoy seeing Kelsey Grammer in Trek.
You assume "people" is some large body of the ST audience who cared about Bateson or Grammer. They do not, and despite dragging Stewart back for Picard--a series that did not exactly return ST to some pop-cultural height, who is really asking for more random TNG-related anything?
Besides their is only so much you can do with bringing Shatner back as Kirk. You know you can't do action stuff with him at his age.
He does not need perform in action scenes. The character is far greater than that.
Exactly.Unless you’re just pandering to the hardcore TNG fans, nobody else would give a shit.
