I would think that the child would be Reynir minor 25

It can't. You cannot increase your bloodline power. This is one of
the reasons why it is so important to make sure you marry well-blooded
individuals.

True lines belong only to those individuals who were champions of
the old gods but didn't rise to godhood itself.
