Had an idea for how the UFC could do Women's Flyweight.
It occurs to me that with the rise of Joanna Jedrzejczyk, the UFC may be thinking about accelerating their plans for an a third women's division. Their Women's Bantamweight Champion is the largest consistent draw in the company, and now Joanna Champion's star is absolutely exploding. She can't headline PPVs yet, but she could co-main most of them, and is well on her way to being a marquee draw. A Flyweight division is an opportunity for yet another star.
So I put together a blueprint on how to put together a Women's Flyweight division, in theory.
The parameters:
-I ignored already booked matches since this is all just proof of concept, and I'm assuming Bethe Correia loses anyway, but I did not ignore long-term plans for SW and BW.
-I tried to compensate Invicta somewhat for the talent that gets taken from them here, since it's quite a lot.
-I tried to replace anyone moving up from Strawweight or going down from Bantamweight (particularly the latter), since those aren't enormous divisions or anything. Each division lost at least one really major component but will recover.
-I almost entirely left out people who are coming off a loss unless it's a loss to someone else I'm taking (but not two consecutive ones).
Result: I got a new UFC Flyweight roster with 18 fighters on it. The BW and SW divisions stayed the same size. Each lost a very important fighter. However, Strawweight gained nearly as much as it lost. Invicta got hit (I took 15 fighters from them), but was compensated enough to maintain viable divisions, and their Strawweight developmental pool is still particularly deep.
I tried to rank the hypothetical top 10 in the new division, which could be used in a tournament (with 2 alternates).

Some key SW/FLW/BW fighters Invicta can still utilize
-Ediane Gomes - BW/FW
-Sarah D'Alelio - BW
-Cindy Dandois -BW
-Raquel Pa'aluhi - BW
-Zoila Frausto - FLW
-Takayo Hashi - FLW
-Munah Holland - FLW
-Roxanne Modafferi - FLW
-Lynn Alvarez - SW
-Alida Gray - SW
-Mizuki Inoue - SW (as much as I would like to take her, I'd like her to get back in the win column first)
-Livia Renata Souza - SW
-Ashley Cummins - SW/AW
-Brianna VanBuren - SW/AW
UFC "Flyweights" I would keep at Bantamweight
-Jessica Eye: has stated she prefers BW because she
had trouble making weight, and is a contender at BW.
-Julianna Pena: only had one fight at FLW, and she lost.
Meanwhile she's a darkhorse contender with a built-in
storyline if she reaches Rousey.
-Cat Zingano: Was already absolutely enormous at FLW,
and is even larger now.
Some fighters I would avoid
-Julia Berezikova: Russian ultranationalist (trust me this is not the sort of attention the UFC wants in Europe).
-Sheila Gaff: one of the dirtiest fighters in the sport.
