How many copies of Jeanne Alter do I need to fully max her out?

I already have 5 copies of her, so she is on NP5. I maxxed out all 3 of her append skills but I noticed that I only have enough servant coins to get her to LVL 116. Allthough if I am correct I should get 60 servant coins when she reaches bond LVL 15 right? (she is bond LVL 14 rn).

The problem is that I know 2 more append skills are coming to NA soon, so I will need even more servant coins. And if I max put her LVL it will leave me with 10 coins only.

Now that her banner is out again, I want to know if I have to get another copy of her to get both of her new append skills.

I just really hope I don't have to pull for her again because then I'// just have an awkward extra copy of LVL 1 Jalter sotting next to my LVL 120 Jalter. Am I just supposed to burn her?...again?

I'm making this post because I heard something about universal servant coins coming out soon, and just wanna make sure if I can use those instead.
