This may be wrong but it's just speculation. I think humans who can perceive the angels' true visage can become angels by using their grace, but they have to keep replenishing it. Since Anna could perceive their true visage even though she was originally an angel and become an angel again, I think humans could. Although if two angels have an intercourse they could make another angel, just like how angels could makes Nephilims. Although I'm not sure where the grace comes from..
