Have you looked at the commentary in Cambridge edition of Divi Claudii Apokolokyntosis? It references a mention in Hermes 92, 1964 pp. 251 ff. contrasting the common idea of life after death with apotheosis.
No nibble on this one? I did find an interesting article (on JSTOR) which discusses the two passages:
Perfume on Lentils
Lionel Pearson
Transactions and Proceedings of the American Philological Association
Vol. 94 (1963), pp. 176-184 (9 pages)
But he’s much more interested in ἀποθέωσις than the bean farce, other than to be skeptical that such a thing really existed, “as the textual emendations show.”
