The hub point is definitely not a bad idea, would be akin to Demon's Souls. ‎  The only thing you have to be mindful of is placing new items/objects/enemies/npcs in that area. ‎  Adding events to maps should work fine with patches and saves, however modifying the location of any of the aforementioned things I believe will break a save game. ‎  In other words, add an object for every warp point youre going to eventually need in your game, and an npc/enemy/item and so on. ‎  You can add in the content to those objects etc later on via events, but you can't add a new item to the map without busting a save game.
