So, a 46 MP FF camera positioned the same distance as a 21 MP FF camera would likely resolve more detail than the 46 MP FF equivalent 18 MP 60D that Bryan used in his tests.
But that reflects real-world usage - you compensate for the crop-factor. What you are suggesting is interesting, too, but given that it's more of theoretical interest I'd say Bryan is doing the right thing.
