They're really not that different at all, and expanding the newhalf tag to include more types of characters intended as such would increase search utility for people looking for newhalves. About one third of all posts tagged as newhalf on Pixiv are also tagged as otoko no ko, and there's also cases like Oozora Hibari, an explicit newhalf created decades before the otoko no ko trope even existed that gets tagged as one retroactively. I see no real problem with retagging these characters, other than the fact that some (but not all) users still want them in otoko no ko searches.
"Almost Femboys" would theoretically work exactly like pool #2138 or pool #6546. A character looks almost exactly like a femboy, but by some technicality, they're not. You could choose whether to have these in your query or not depending on whether these technicalities matter to you.
This seems more like a "should we do this now or later" question rather than "should we do this at all". I don't mind implementing it at a point where it's not very controversial (whenever that may be), but I don't see any harm in discussing it now either.
Possible point of reference: Akizuki Ryo had a gender debate very early on from people who wanted Idolmaster to be 100% female, and some people ignored obvious hints that this wouldn't happen. As soon as the game's contents became clear, we ended up tagging all these old Ryo posts as boys unless proven otherwise.
More than half of the art work showed in the link you used doesn't appear here, so i don't think this happenstance is so useful for us. And they're really different, as you yourself pointed out, the majority, two thirds, don't see the two as interchangeable.
Cases like Hibari-kun are more complex, since terms like Newhalf were used as an umbrella during the time of the creation of the series, the same goes to Okama. We use the term Otoko no ko now, because the majority agree that the character, who was created to be a boy for subversion,fits inside of Otokonoko better than it fitted inside the term Newhalf. But there's a lot of space to argue how to properly label ambiguous characters like that, or if we can even find a proper labels for them.
You pointed the problems, users want those characters in the Otokonoko tag, and they don't fit inside our idea of Newhalf, so retagging them would generate more problems and muddle the labels, making people get confused regarding their proper usage.
What would those technicality be? A femboy is a boy who's feminine, if we include characters who aren't boys or that don't look like boys in any way, we would generate problems and take away from the term.
Ryo case is different, they always had the Otokonoko aspect by what i know, so it wasn't a complete change on the character or something hard to accept, with Bridget is different, we don't know if people are gonna accept this change or if it's gonna take over the past image, and we don't know if this change is gonna stick, we don't even know if the character is gonna appear in a future game, that may not be produced.
