What would be the best way to model iberians?

[Jingle Bell]

I want hear some opnions abt this topic, since i just realized that dont (at least i never saw) any samples from the NW/W IA ( the places which was the most celtic in iberia), also its strange that iberians despite not begin of full Iberian IA stock for some reason still have more Yamnaya than even Celtiberians, why? Visigoths? Northern settlers (which prob descendants of the "full" Celts like Gallaecians)?
I got 2 samples from 250 - 520 CE from Central Portugal

they were almost full of Iberian stock + a bit of Roman and NA but they still have 25% - 30 Steppe, which means that their ancestors (Lusitans? Since they are from C. Portugal) werent too far from that too
So what modela i should test? I am starting to get no more ideas abt how i can make a more accurate model . . .

the problem with the Visigoths is that they probably overlap with the Celtic genes of Iberia or that they came here mixed with people from east europe/balkans etc...

Visigoths , when they arrived Spain were already mixed with half Europe of that times. They were resettled several times during the last stage of Rome.

In Spain we have some Andalusian "Visigoths" (buried as Visigoths in a bordering deffensive settlement with the Byzantine territory in Andalusia) and many were genetically like Canarians seeing their NA admixture. On the other hand, some of Catalonian "Visigoths" samples show more Northern/Central European admixture+Iberian , in diverse proportions depending on individual, from some whose admixture show them as something close to Northern Frenchs, others Southern French or directly Iberian.

They could be descendants of Christian coastal North African allies of the Visigoths, and used by them to populate border areas that had been mixing with native Iberians for one or two generations, had a specific name and were half farmers half warriors.

yeah i know nut i mentioned the visigoths because they were the largest germanic group that settled in Iberia about the suebis maybe the had some impact you cn find haplogroup I1 in Galicia and norther Portugal
