West/Gallaecia/Lusitania were the part of Iberia with less contact with others "Low-Steppe" groups like Iberis or Vasconi, they preserved a very strong Hallsttat origin, and from the little we know they would be a bit more Steppe shfted than Celtiberis, we got the Conimbriga & Miroiço samples, which are Hispano-Roman samples from areas either Lusitani or Celtic habited, and even Conimbriga having abt to 20% Roman + NA & Miroiço about 40% they still scored more or at least abt Steppe as Celtiberi samples scored, my guess is as Miroico & Conumbriga are Roman/NA admixed and even with that scored ~28% Steppe, the "pure" Pre-Roman habitants of that area would be abt 30%+ imo, prob clustering some what Occitane or Northern Italy unlike more EEF shifted Basques, and its also important to remenber that Portuguese (better saying Galegus-Portugues) originated in Northern Galicia and that reconquistadores/settlers migrated south and most Portugueses prob descends more from that guys rather than the Muladi Pre-Reconquista population, so the "Celt" of that Portugueses descends are more likely part of Castro Culture/Gallaeci complex, that were more Hallstattized (at least culturally) than Lusitanians so thats also indicated that MAY also were more Central European loaded, but who knows
