Salam `Aleykum, If you're a Shafi`i why not follow Shafi`i Fiqh with complete disregard to what Salafiyoun do? for example as far as Kuniyah is concerned your Imam which you follow (i.e al-Shafi`i) had a Kuniyah and he used to be called abu `Abdullah. As for Niqab a woman must cover her face in front of non-Mahram men according to al-Nawawi, so just follow the Madhab and don't think about what others so.
