WI: O'Duffy's Irish Brigade in Spain more successful

In 1936 Irish fascist Eoin O'Duffy assembled an Irish Brigade to fight for Franco in Spain but what followed was basically Murphy's Law come to life as poor discipline, drunkenness, a lack of combat and an infamous friendly fire incident among other things took their toll on the unit's morale and standing among the Nationalists (with Juan Yague reporting that "the military efficiency of this unit is absolutely nil"), resulting in O'Duffy and the Brigade being sent home in disgrace.

What if the Irish Brigade hadn't been a complete failure, could O'Duffy's fading political career receive a boost out of it when he returns to Ireland?
 
Perhaps he might go on down the Leon degrelle path, and turn the brigade into a corprotist corps on the eastern front.
