Any alternative is generally better than gotten.
This. Both of your examples are VERY informal.
example of a formal one?
"Have you retrieved . . ."
More to the point, "Have you examined . . ." since, formally, the person may have "retrieved" but not examined . . . it. And you do wish to know if they've looked it over, no?
However, as fussy as I may appear to be to others here in matters of grammar, I would opt for the slightly friendlier and more "conversational", "Have you had a chance to look over . . ."
