I'd be interested in that headcanon! And I'll include the whole quote in context later, but I just wanted to clarify that the "plan" is from early 1762 and more teasing and wanting to see her again, not related to any official end of war receptions at that point.
re: "maman" - he uses that from the start! There's even one where he's talking about both of them - maman vs. mère - which was a tad confusing for a moment. My subjective impression was that he got even more affectionate and clingy after SD's death, but there's of course no way to tell if that wasn't just due to his general state of mind during the war, particularly because there aren't any letters between 1745 and november 1760.
