Majority (more than half to be safe, half is pushing it but maybe still possible) NW Euro. For non-euro blood, 1/4 maximum, and any mixture must be with a non-garbage people. Patrilinear line is preferred in all cases.
Passing that benchmark would warrant individual consideration on a case-by-case basis.
Such individuals should breed back into NW Euro if they pass, and should stay as a small minority in any asatru group, an exception that proves the rule.
This is off the top of my head. Feel free to add your thoughts.
