You can, but the cost will be great.
Idk what we have in the way of rerolling accounts, but securing band Kazusa in minimal rolls will give you your best shot. After that you rush missions and main story to level up your account and collect pyros.
Dont go spending any of them after Kazusa, they all need to go to bluefes in December for Seia Swimsuit and Dress Hina. If you rerolled for Kazusa on your first 10 pull, you could do it all in 310 pulls cause I'm p sure Dress Hina is on banner for fes. Quite doable.
