I would like to give another addition to this.
Since Hierophant Green was introduced as the ranger of the group as it is a stand that focuses entirely on long-distance combat, i feel like the requiem version of it would be unlimited range.
For example, HG's emerald splash could snipe anyone from wherever it wanted to be, from nation to nation, planet to planet, galaxy to galaxy, or it would even able to snipe anyone who's in another timeline or a dimension out of the JJBA universe.
