I'm not sure what you mean by "vessel," but if you mean the actual vessel, as in the Golden Key, it stays pretty consistent. The vessel can shapeshift, but it's always just a key.

If you mean the person possessed by Wrath, Wrath is not the only demon to influence and possess multiple people over history. And, well, it could be Gallerian's wife got ahold of the key at one point and was possessed but if that were so, it would be a lot harder for Nemesis to have gotten it. It also wouldn't make much sense narrative wise since she as a character didn't have a lot of time to do anything wrathful.
