If you want to get the mod completed in a reasonable amount of time, I'd suggest trying to build it to a similar level of quality as the original mod with something playable beginning to end.
Once you have something like that that can be suitable for a release, then you can start looking to improve upon it and add new stuff or things the original mod never had.
Otherwise you can just release the version that roughly matches the original and be done with it.
It's good to have ambition but too much can kill projects. Keep in mind the creator of the original Life's End never finished his more ambitious sequel, Time's End.
