Also different versions of "tests" like this sounds like a pretty good idea, have a writer writer a more usual story for the character before being allowed to branch out, that way at least some characters can be more consistent.
Then again, for something like that to work, it'd need someone to actually know and care for such tests to begin with, and for the writing gimmick at DC not be "throw **** at the wall and see what sticks".
Plus a test like that would make Bendis not have a lot of characters to write, don't think DC would want that after making such effort to get him
