Dear J. As-salaamu alaykum. Absolutely not. Not a single Muslim scholar interpreted Khatam -an-Nabiyyeen other than the last and final prophet, because such a position is already confirmed in the Qur'an and the Sunnah. Please refer to question/answer 3331 too for detailed information. Thank you for asking and God knows best.
