It is definitely an important scene in the film, but it's more important for Scotty in terms of story and character development (as many sacrificed minor characters are in films).
I don't know, it feels like making the toy of him and not of Scotty is showing a misunderstanding of his place in the film.
They talk about this in the video. Nacelle is almost making these figures as a response to Playmates’ line which is nothing but the most well known characters. I think in the future they’ll get around to Scotty (but do it in a special way, like Scotty from Relics complete with makeshift arm sling).
I guess there are a lot of lesser-known characters that I would have gone for first:
To name some from across the classic shows: Finnegan, Vash, the female changeling, Icheb, Major Hayes.
Aside from Finnegan (that's just personal preference, you could do a multi-episode minor character like Sarek), all of those characters had more effect on Star Trek storylines than Peter Preston.
I mean look at the other characters they're going with. I wouldn't exactly put him on the level of Rachel Garrett or Tuvix or Jellico.
