One of the problems is the nature of the beast when it comes to Hollywood at the moment, of whether you could get that kind of investment for a non-action oriented Trek movie? Once you're talking about a theatrical release, the powers that be at Paramount want something action-oriented and have used Wrath of Khan as a template for a long-time as to what they think a Trek movie has to be (i.e., a movie centered around stopping a big, bombastic villain with "universal armageddon" at stake).
I remember it being argued as to whether you could do a movie like The Motion Picture or even The Voyage Home given the current dynamics of Hollywood production. Could you do a 2-hour Trek movie that was an exploration of a weird alien encounter that doesn't have a villain or a 2-hour Trek comedy with whales that has no big action set piece and get it greenlit by Paramount executives?
I think that it's more likely that if something like that were to be greenlit today it become something that happens for a streaming service, either as a TV movie or limited series, instead of being a theatrical release.
