It'd be a really interesting idea for sure, if not for any other reason than to see the old park again and maybe even get to see parts of the old park that we didn't get to see in the original film.
With that being said, while I don't have any issue with the sequels forging their own identity and taking on a different tone than the OG films, I kinda feel that a film that takes place alongside the original would have to retain a tone and feel closer to the original JP, which might prove difficult. Also, there's a strict continuity that would have to be adhered to as well.
Still, it'a an intriguing idea.
