I think my best guess would be to say that it’s like asking what would R’ Akiva would hold if he were R’ Meir, regarding “chosh’shin l’miut’a” (or any two members of Chaza’l, on any issue in Sha’s).
The obvious difference being Mesorah vs. life experiences. A more correct dimyon (IMHO) would be supporting Am Haretzim and Rebbe (during the hunger), in which Rebbe concluded from his life experiences that taxes come from Am Haratzim.
Otherwise I think your answer is a good one.
