Again, your theory about Scorpion is an interesting one, but nothing that is verifiable. The overall attitude that I can find is one of liking it, and even the producers found it to be an enjoyable episode.
Part One, maybe.
However, that does not mean that I must accept VOY as it occurred because the production staff chose a limited plot line. VOY does not get special consideration because of poor choices.
Like I said, series rushed into production before these flaws were detected. Compare how long they took putting DS9 together to Voyager's rush-job.
Unfortunately, it was TNG style storytelling, but without the characters that grounded that series.
This is why I say the show came at the wrong time. If they'd waited til after DS9 not only would they have been able to see the flaws in the premise and think of a more complete one, other shows with similar premises (LEXX, Farscape) would be on the air so they could show them as example to their Bosses as to what kind of show they wanted to make.
You may be right about the casting, and a smaller cast may have made a difference, though TNG and DS9 made do quite well with a larger cast, to the point that Rom got married.
To be totally honest, I think TNG struggled a bit with its Large Ensemble cast. But it was the experimental cast wherein they first tried the idea so I can understand.
DS9 only got their cast to work because of their big Galactic War storyline, and even then some of the cast were still unneeded (Dax).
Sorry, I can be pretty generous, and there are aspects of VOY that I enjoy, but there was more bad, than good, in my opinion. It just lacked a depth and consistency to be interesting, in my opinion.
And I can agree with this.
