PC:Spanish HRE

Is it plausible that spain+portugal could develop into a HRE like polity post-reconquista. How would such a state behave as opposed to the Spain OTL.
 
Doesn't seem liekly with a reconquista like IOTL, after all the HRE by this time had already fractured and was in some sense in a process or attempt at reforming, it seems unlikely that a region would become more decentralized during this period especially from a position like the Iberian kingdoms.

To me the easiest way would be either have the Visigoths survive and slowly fragment or have Frankish overlordship at a point or another and have decentralization happen from there.
