Is It Permissible for Two Families to Share One Cow for Qurbani by Splitting the Cost 50/50?

Assalamu Alaikum wa Rahmatullah, I have a one focused question and few follow up question which are all part of that question. Let's say, My family and our neighbor's family are purchasing one cow together for Qurbani. Each of us is paying 50%. Is this type of joint Qurbani permissible, or is it considered Bid’ah? each family mention multiple names to the person who slaughtered it for them after it is slaughtered and they are making a dua, is this a valid practice? and if it is, how many names can 2 family mention? (sorry if this sounds strange as this is something i see often in my country and I'm unable to find evidence from the Qur'an then Authentic Sunnah and Salaf As-Saleheen. Jazakum Allahu Khairan.
