It could. My understanding is that it were the Alans who were the "senior component" of the Alan-Silingi-Hasdingi triade.
Have them beat off the Visigoth attacks which in OTL savaged them and you are good
You could reverse the OTL events - have the Alans take in the weakened Vandals.
And you can have the Alans replace the OTL Visigoths as the rulers of Hispania.
With some luck you'd have Spanish aristocracy today claim Alanian descent.
Besides national/tribal identity the Alans will be thoroughly Romanised in language and (most of) culture before the 6th century is over. They don't even have a Holy Book in their language (Ulfilas Bible for Goths and Vandals).
For the shit and giggles the Visigoths - without Spain to fall back upon - fight the Franks tooth and nail and win in 507.
Thus Gaul splits forever along the Loire, with Francia to the north and Catalonia to the south. Burgundy stays independent.
With less exposure very few of the Salic Franks ever Romanise - the Franks gradually Germanise north Gaul.
There still could be a "Walloon" area, with Frankish speaking nobility and peasants speaking Harry Potter type of Latin.
