As you know these schools of Islamic jurisprudence are just a curation for a better understanding of the orders and tenets of the Book (Quran) and the Sunnah (the tradition of the Prophet).
There is no harm if any Muslim opts for a given school of jurisprudence (mad’hab) in any aspect, and there is no harm if he even moves between these schools.
They are all sourced from the Messenger of Allah.
However, this does not apply to scholars [who study a specific school of jurisprudence]. Allah knows best.

كما تعلم ان هذه المذاهب ماهي الا عملية تنقية لاستيعاب الأوامر والاحكام وان كان الأصل الكتاب والسنة.
فلا حرج علي اي مسلم ان يقلد اماما معينا حيثما شاء وله كذلك ان يتنقل بين المذاهب.
فكلهم من رسول الله مقتبس.
اللهم الا المجتهد فليس له الا مذهب أمامه فقط.
والله اعلم.
