Possible to change size of cursor with Cursor.SetCursor?

The game that I am creating is a pit pixely, and I want the resolutions of the graphics to look a lot like each other. Without tinkering with actual resolution size (making the cursor generally bigger), is there a way I can make the cursor texture bigger? This is my current code for changing cursors:

 CursorMode cursorThing;

 void Start() {
 cursorThing = CursorMode.Auto;
 }

 void Update() {
 Cursor.SetCursor(textureToReplaceCursor, Vector2.zero, cursorThing)
 }

I'm also using a sprite that I am converting to a texture with this code:

     void Start() {
         public Sprite exitRoomCursor;
         public Texture2D exitRoomCursor_text;

 void Update () {

     exitRoomCursor_text = new Texture2D((int)exitRoomCursor.rect.width, (int)exitRoomCursor.rect.height );
     var exitpixels = exitRoomCursor.texture.GetPixels((int)exitRoomCursor.textureRect.x, 
                                                       (int)exitRoomCursor.textureRect.y, 
                                                       (int)exitRoomCursor.textureRect.width, 
                                                       (int)exitRoomCursor.textureRect.height );
     exitRoomCursor_text.SetPixels(exitpixels);
     exitRoomCursor_text.Apply();

But that doesn't seem to restrict the mouse size itself, I believe. But at least I'm showing you what I'm doing here!
