The plot for the final act of Star Trek V is rather similar to Who Mourns for Adonais? .
The God thing could even be a member of the same race.
I think there's enough there for a dedicated fan to do a Revisted style redux.
The film will never be a classic but it's nowhere near as bad as some people make out, neither is Nemesis which almost identical to the current film which everyone seems to be getting so excited about (even if it was a virtual remake of TWOK).
First Contact on the other hand is vastly overated, it's basically a remake of Aliens (which was a remake of THEM!) it still got some nice bits in it but it did also introduce the bloody Borg Queen which contributed to the dilution of all that made those Cyberman/Cenobite hydrids so chilling in the first place.
Other than TMP all the Star Trek films were just glorified television episodes (usually rehashes of OS episodes, even TMP is guilty of that but at least it looked cinematic, but lacking any of the originality of the mother series) including the Colonel Abrams one.
