I still disagree that bringing Steve back hurts his sacrifice. The drama would be in it happening against his will. His sacrifice remains under those circumstances. There's nothing cheapened because he wouldn't have been looking for a get out of jail free card. He intended to, and did die to save a village. That does not change if celestial means brings him back as they have in the past in the comics.
So to me its still very much an option. Again either that or a descendant via the family line continuing from a sibling or something. Main point is, you bring Chris Pine back. You don't cast a poor man's replacement.
