I'm not the OP neither have their problem, but I can't remember names. I know who the person in front of me is, we can talk pleasantly about everything - I have a good memory otherwise - but I can't remember their name to save my life. Luckily they very seldom notice that, if ever. And I won't tell, obviously.
I'm similar, and yes, there are easy options to replace person's name with, as long as you're putting a bit of thought into what you're saying so as not to paint yourself into a name corner.
Ironically, I'm insanely good at remembering faces. But it's kinda useless because of the name thing (and equally, the face context is also difficult).
