Following other Mazhabs in Salaah

Hanafi performing sajdah tilaawat in Surah Hajj behind a Shaafi imaam

Q: If a Hanafi performs salaah behind a shaafi imaam, and the shaafi imaam recites the aayat of sajdah on the last page of surah hajj (which is an aayat of sajdah according to the shaafis and not the hanafis), then the shaafi imaam goes into sajdah and the Hanafi muqtadi follows him in sajdah, then what is the status of the hanafi muqtadi’s salaah? Is his salaah valid or does he have to repeat his salaah?

Hanafi Imaam reciting qunoot in Fajr Salaah in a predominantly Shafiee masjid

Q: When the Shaafiee Imaam is not here, the musallis ask me to lead the Fajr Salaah. Since I'm a Hanafi, will it be appropriate for me to read qunoot with the niyyah of qunoot e naazila so as not to create confusion. It is a Shafiee masjid and many people are ignorant about these fiqhi ikhtilaafs.

I remember once a Hanafi Imaam led the Fajr Salaah and he did not read qunoot. After salaah there was a commotion and people started talking to one another that qunoot was not read. Please guide me what to do.
