The ENDING "gat/get" is used, when something happens more often, like talking/chatting. It can be uses with different words.
"we never have a conversation" should be accepted, because as I know: Beszelget = Having conversation
'conversation' is a noun. The Hungarian sentence uses a verb, so, other things equal, a translation into English that also uses a verb would be better.
Yours is an over-rigid way of thinking. IMHO, if it sounds natural in English and gives the correct meaning, it should be accepted.
