The Germanic tribes (more a linguistic group, than a “blood type”, includes such diverse groups as the Danes, Icelandics, English and Franks – and probably a good many others that assimilated into other populations.
BTW, do we have a tradition of “good” Amalekites working to undermine the bad “Amalekites”? If not, the hpothesis that the Amelekites are the Germanic tribes, fails.
