That itself is not something all ethicists would agree with. Finally, my bachelor's in philosophy comes in handy.
I don't understand the point in even writing an article like this because it's impossible to begin without staking out your moral positions, and at that point 99% of the work is just writing a philosophy paper. I don't think you can even say that most philosophers would agree that moral reflection promotes moral behavior, because you'd have to get them all to agree on what moral behavior is - or in other words, you'd have to solve the problem the field has been trying to solve for the entirety of its existence.
