I haven't seen it. Oddly, despite being a big sports fan, I generally find sports shōnen to be kind of boring.
I actually think this is interesting and may even tap into some of my own feelings. Even though I definitely identify as cis-straight, I do have a strong internal feminine side, even if it's a bit subdued. I have a Sailor Moon costume, but I've only dressed up in a few times. But when I do, I go all out.
And I do mostly play female characters in MMOs. And while I'm not going to deny there's probably some bit of objectification to it, that's really not what it's about for me. I don't participate in the 'chain mail bikinis' of it all. I create detailed bios and really try to cultivate a character. For me it's more about experiencing the adventure as a strong woman than it is just staring at pixilated asses for 100+ hours.
I mention all this because, in any given MMO dominated by boys playing girls (which is pretty much all of them), certainly 90% are strictly there for the digital waifu. But I noticed over the years that there are a lot more (especially in certain games) like me than one might think. The thing is I've also noticed a lot of them are hugely transphobic, which has always seemed really odd to me.
So even if you don't intend it to, I think your story could work well as a 'teaching metaphor'.
And this has the added benefit of pissing-off all the right people.
