Why not.....there's no physical law or principle denying it or preventing it from existing.
You can't add to something infinitely small and make it infinitely large, or any size at all for that matter. Adding an infinity to an infinity still only makes it an infinity. In defining a large and small infinity, you have to set an arbitrary point somewhere between the two that delineates between large and small. Remember what I wrote earlier, large or small are conventions of scale, not vector (numerical) conventions.
