We use this approach. You can find the property you want using JObject's SelectToken(). Yes it does support JsonPath.

public static class NewtonsoftExtensions
{
    public static void Rename(this JToken token, string newName)
    {
        var parent = token.Parent;
        if (parent == null)
            throw new InvalidOperationException("The parent is missing.");
        var newToken = new JProperty(newName, token);
        parent.Replace(newToken);
    }
}
