Is this even somewhat achievable?

I heard she’s getting a rerun with nefer around 6.5, and I want to try and get both her and lauma along with her signature weapon, is this a realistic goal in the time there is till then?

There is a few things that I’m hoping will make it more achievable, mainly:

I’m already at 85 pity

I’ve got welkins that’ll last way past their banner

I’m planning to get this BP and the next one to level 50 (with the purchased one)

I’ve got a lot of really rich areas like Fontaine and natlan not really explored all that much

But I’m also not guaranteed for either of them so I’m just hoping I can win my 50/50s on them both
