I am not so sure we WILL get to Angela 'embracing' her birth family. She has been raised in the Angelic culture for THOUSANDS of years, and as far as she knew she WAS an angel, just one without wings. You don't just give that up in a day or two, even if it is revealed your entire life is a lie. I think Loki realizes this, and it's why he was tempting her with the stars and adventure, rather than her Asgardian family, even though I am 99% sure he knows exactly who she is, even if Thor is too dense to grasp it right now. If he can get her to leave the angelic realm because adventure before Odin seals off the Angelic realm again, (maybe with Cul inside as well?) then she is at least in a place where they can check up on her, and she can maybe see that the Asgardians are not the evil people she has been told they are. That is likely the best they can reasonably hope for.
*edit - Oh, and while the fact that they had fleets of warships was a little strange to me as well, then I remembered that her Spawn continuity IS intact, they have said this in a few interviews, they just can't go into any detail about it in the comics for legal reasons. So they are not sealed in a little bubble, the angels do have access to the Image universe, at a minimum, which means their fleets are not necessarily useless. It was only 616 they were blocked from.
