St Anselm's Ontological and the Ontological Argument

[paradoxo]

The argument might have provoked less debate if St. Anselm had been explicit about the convertibility of the transcendentals.
1. Goodness and being are interchangeable.
2. "The Aliquid" is the greatest conceivable being.
3. But the greatest conceivable being is ipso facto goodness itself.
4. So the Aliquid is goodness itself (2, 3).
5. So the Aliquid is being itself (1, 4).
6. But being itself necessarily exists.
7. Thus, the Aliquid necessarily exists (5, 6).
I wonder if this version can survive the Angelic Doctor's objection in the Summa Theologiae; it doesn't seem like we must suppose that we know the Divine essence to present this argument, certainly no more than when we offer any of the proofs St. Thomas developed in his Summa Contra Gentes...
