Perhaps. Or perhaps that bloodline and family affiliation business as a Jewish traditional cultural obsession into which God fit His Son in order to make an impression on the Jews using things he knew they would understand and value, as opposed to there being any intrinsic value in that bloodline.
I would go farther than you when you say "All can gain Salvation through Jesus Christ". I would say, to more perfectly fit the Gospel, that all who gain Salvation do so through Jesus Christ (although, to go a step further, it does not appear that all who gain Salvation REALIZE that it is Jesus Christ who is saving them until after they physically die). Enoch and Elijah, too, were saved by Jesus Christ, although they couldn't have heard of him until they were taken up into heaven, perhaps BY him, or perhaps by angels, etc.
And Adam called his wife's name Eve; because she was the mother of all living.
God told the Jews which lineage priests were to be from. When they became lazy & disobidient about it, a price was paid.
WHen the sons of God came down to earth & bred with the daughters of man, the intent was to mess up God's plan by muddying Adam's line with the seed of fallen angels. If there had been no one left with a pure bloodline, Jesus would have been as much a son of the fallen angels as he was a son of man. God needed Mary to have a pure bloodline.

I agree.
