Interchangeable components even if aesthetic would be a nightmare for OEMs/AIBs. They need to standardize the cooling or issue strict warranty terms to avoid problems.
Sapphire does or did allow
some fan and shroud customization on their 2-fan Nitro+ GPUs from the Polaris series; fan customization covered their 92mm-using GPUs while the backplates and shrouds were for the 590/580/570 editions.
That is quick of HIS to captilize on the recent "cute edition GPU" trend.

I mean there are a lot of anime lovers who would gladly buy these.
PC hardware need some feminine touch alright~
I'm tempted to get the Galax one just for the sake of it. Already got the Yeston Cute Pet 580 to build for my youngest cousin who likes cute things, and just waiting for the Yeston "Sakura" 5700 XT to become more reasonably priced before snagging one of those. Though I do wish Yeston did what Galax did and have the backplate image properly "facing" towards the case window instead of towards the mobo.

As to the topic, I'm sure there's a "HIS and HERS" joke somewhere, but would probably result in a "did you assume gender" comment. That aside, the blue one wouldn't be all that bad for a Navy-themed or colored build.
While I do appreciate the current trend of GPU designs, some novelty variants are never a bad thing; half the PC building is the looks and personalization after all. Really though, I wonder when will we get full OLED-wrapped GPUs. As in; the entire shroud and backplate each has an OLED screen layer for next-level personalization (of course, with vents/holes cut where necessary). Turn it off for a glossy black look; turn them on and set the colors or animation themed to one's mood or favorite game. Blower-types would have a more continuous OLED screen "canvas" to play with, whereas fan-types are more similar to the Galax anime one above; except with OLED screens instead of inserts.
