I don't believe that is possible. If it were possible, it wouldn't be called a blindspot. Of course a mirror should be well adjusted, but I don't see how it substitutes for checking the blindspot. Try it in a driving test; you will fail the test.

I literally have no blindspot in my vehicle, my parents' vehicles, or the vehicles I have rented except the Chevy Malibu.

When the mirrors are positioned properly, other cars transition from the side window, to the side mirror, to the rear mirror.

There is literally no spot that a vehicle or person standing in the next lane, is not visible.
