He'll never direct a mainline/offline FF - either because they won't let him, or because he won't want to because they'll want to force him to engage in the crude female exploitative design that that's made the mainline series so embarrassing.
Yeah, imagine if he was forced to make a game where the main heroine looks like Minfilia 2.0.
NeoGAF would have to make a thread about that!
I think the way people talk about FFXIV includes a lot of double standards (ergo "it's the best final fantasy ever!"), the female armor designs is one of them.
FFXIV 1.0 was somewhere around 90 to 100% gender neutral on gear (FFXI wasn't to that degree, but it was far more modest in general - some exceptions, such as Dragoon AF, which I will be mentioning for FFXIV). The moment Yoshi-P came on board that immediately changed with the female versions of Bard and Dragoon armor being very different and sexualized at that - female Dragoon is missing huge chucks of armor, include an open belly, and female Bard walks without a shirt under their coat, for maximum cleavage and belly exposure.
When A Realm Reborn released, they introduced the very different and sexualized default race armor, which happen to highlight the new breast physics in the case of the new, extra-busty female Roegadyn; the double standards are so strong for FFXIV that when the rather sexual female Miqo'te default armor and pose appeared as a crossover in Lightning Returns (arguably the most overtly sexual pose in the game) there's was highly vocalized distaste over it by the very same people who now praise FFXIV to high heavens.
Many of the new armor sets released also featured some very prominent differences when equipped by male and female characters - namely, the male version wears pants and the female version wears a mini-skirt. Any sort of pointing towards subligar (a holdover from all the way back in the early days of FFXI) or bathing suits/joke armor is a distraction on this point, because a gender difference in gear (and one that is unquestionably sexualized) has a straight line from Yoshi-P's new direction that only became stronger in the new version of the game. What's noteworthy about this is that these are gear sets that every character must wear, not what just one character named Cidney/Cindy wears - if you want to wear the iconic Dragoon set (which wasn't really a bad idea mechanically in 1.23 era, different from 2.0+ breakneck progression pace) as a female character, you have to have your belly exposed; if you start as a female Miqo'te, you begin dressed like a catgirl schoolgirl (meanwhile in 1.0, you just looked an adventurer, maybe with an open-shirt, but that was gender-equal). I was thinking about flooding this posts with images as examples, but I don't think it's necessary unless people simply don't believe what I'm saying.
Honestly, I don't mind this stuff so much and I don't mind if people like it. I was very disappointed when they changed the tone of the original game to be more sexualized and cliche'd anime, but that's neither here or there. What bugs me is the ridiculous double standards people have for this game. Imagine if a single-player Final Fantasy had implied gang-rape in a quest (required by the main scenario) which is immediately thrown away by the cutscene's end? Would be hell on earth.
For comparison: Here is the Minfilia design of 1.0 (right), which was remade into a different character in 2.0 (left).
EDIT: Gear swapping can/could have fit fine in FFXIV or other games. You don't need to have a bunch of macros or anything, just create a system where the character can change to two or three sets of armor a la Lightning Returns. I get what people say about balance in terms of gear having interesting effects, but the lesson many games (e.g., fighting games) will teach you is that balance is boring. Personally, I find highly-pointed vertical progression to be excruciating, and possibly a metaphor for the pointlessness of work or life.
