I'd say your brief explanation works on many levels, in the "quick-and-dirty" sense.
The other obvious possibility is that Jack Torrance went insane and imagined everything with WAY too much time and isolation on his hands. Kubrick of course, declined to provide a definitive answer and wanted the viewers to come to their own conclusion. (Or he did not care one way or another.) However, given the documented and lengthy history of horrific events that spanned decades, I tend to think it was a combination of Jack's diminishing sanity and paranormal/psychic influences. So we never truly know what the "blend" was.
All of the above stated, my take is that the hotel was, in effect, a massive "focusing lens" for those with paranormal ability, latent (like Jack) or powerful (the boy). It was definitely malignant/evil. The wife had ZERO ability, so the hotel only was able to get her to see what it want her to see when it was "super-charged" with psychic energy, near the finale.
The hotel knew that the boy was a threat since he could effectively summon outside, and powerful help, who presumably "thwarted the hotel" for years if not decades while he worked there. (He knew that an unstable person like Jack would be dangerous, and the young boy with the Shining would be targeted; but he tried to not care and do what he could while talking with the boy). The boy could influence the wife and possibly Jack to leave. He had to go. The wife was totally incidental, UNTIL she got the best of Jack and locked him in the storage room.
As for Jack always being part of the house "staff" or a reincarnated version of Grady. I like your answer, while simplistic, works well.
