I still don't understand the logic behind using it for future purposes and intent as a central meeting place for all the kage to attend and as a place for neutrality.
Never has there been any effort for all the kage to gather there, since it would take a colossal amount of coordination and time. Whenever the Senju Clan on SL met, we used the Paper Lantern Technique because it was the most beneficial thing to use when concerning those two aforementioned factors.
As for a central place of neutrality, that's pretty much what the ambiguous wilderness serves as already. The zones serve a purpose for that too, and I can name plenty of people who are Missing-Nin, or have a consistent unaffiliated status, who have used them as a means of a place to hide-out from villages and nations.
Jiseigakure is literally a double-OOC board as it is right now. And I don't think that turning Hoshigakure would be a great idea, since it's kinda hard to get to and another party already claims to use it consistently for RP. Making another new village board would take some time, but it could be possible.
But what would you guys feel more comfortable with? Asking for Jisei to be renamed to Ame and save everybody some time, or ask for a completely new village board to be implemented which would require input from the community to add shops, instances, travel conditions, forest-related events if it gets a forest entry point and other things?
