Because this is just a character, it's not some elaborate boss. When people data-mined this model it was
catalogized as a Femroe model so that Femroe could wear it, it uses Femroe's scaling system and by all means is just a body/ outfit that's set up so that only Femroe can wear it.
There's really nothing special to it, other than the fact that it doesn't look like a Femroe's body shape.
(First off, this is not a miqote. Would be great if we could stop grasping at the disconfirmation bais arguments ... we all know how miqote look and what their ears look like and where they're placed on their skulls.
Looks exactly like the mural, trying to convince yourself that it's not what it clearly is aint helping discussion)
It's not silly at all.
The devs aren't blind, and they are aware of why Elezen look the way they do. So when they want to make attractive Elezen bod NPCs they give them better scaled heads to fix the glaring problem. Aymeric isn't just a unique face, he and other unique Elezen NPCs have better proportioned heads for their bodies as a means to make them look better and more appealing. They didn't repeat the things that made Elezen less popular than they could be when they made Viera females and Au Ra males.
So, applying that to this ...
if someone wants to ignore the glaring proof from this art that this in game character was intended to be a Hrothgal before something in this hellish year made them change that, then you have to think that this is what they think a prettier, better looking Femroe would be. It's not a secret that Femroe don't get love from the story (I think they legit have the fewest prominent NPCs in the game of any race-gender option. Hell, I think there's more dead Hrothgals than there are important Femroes), and it would be incredibly naive to think that the devs haven't taken notice of their feeeeew few numbers.
So if this is what they make the
first noteworthy Femroe in years look like, then that's a clear sign that they prob aint interested in making a Femroe 2.0 as a race.
It's so puzzling, I've never seen a good reason to think they would look past all the popular females and try to make em look like Femroe, yet people simply assume that. Makes prefect sense to me that they would take the most popular non-1.0 reg sized female bod (Au Ra) and combine it with the most popular and new taller female (Viera) to make something new.
