It seems to me the script was problematic from the start with several treatments submitted, each handling certain things in drastically different ways, yet only Garrett Fort got screen credit. The tinkering continued throughout the production, which tells me they were never satisfied even with the so-called final shooting script. That's why, in my opinion, I don't think it's fair to use it as a bar by which to determine what the extant film should have been. If Browning and Junior Laemmle had their reasons to deviate from the script, then whatever their vision was is what takes precedence. In other words, I don't see how a fan edit of the film based on the script approximates what Browning envisioned the film to be when he himself considered the script expendable.
