Technically, this is permissible but it would be something innovated as it was not done by the Prophet salla Allahu alaihi wa sallam or his companions

My question is when in salah first of all we recite the fatiha and then add it with some other surah. Now, can we pray like first we recite the fatiha then adding any other surah to it we add fatiha again can we pray like that ? Because one person was saying that the whole of quran consists of surahs where fatiha is also a surah so what difference will it make if we recite fatiha and then fatiha. Is this act permissible or what is the correct verdict.
