I think it is plausible.
But let me pour some fuel on the flames.
Have you considered makadur to be makidoor of the gurgura dir. They lived in the same area with their mandaluq brothers
Maybe they were adopted by the Gurgura after the war since many clans dispersed and some had to regroup and Gorgorah were mentioned separately in the Conquest.
The Gurgura have always moved as one clan with one Ugaas, it is logic defying for Habar Makadur to be a subclan of Gurgura 500 or so years ago when the Gurgura themselves were less in number. Moreover, why would they be listed separately from Gurgura? Habar Maqdi ain't the Makidoor of Gurgura guys.
