While funny, I don't think that would happen. It's been shown since Crystal Seminar that transformed who fully descend into monstrous mindsets will be vaporized instead of changed back into humans.
Torgamous is right. Moon Healing Escalation was never used at Crystal Seminar, only the much weaker anti-mind-control Moon Tiara Stardust attack. Which is designed for liberating crowds of mind-controlled humans, not for purifying a youma.
Judging by Ahma's behavior and her reaction to us flexing on the hospital while she was in the AoE, she's likely to end up loose atoms instead of a human.
To be fair, the Moon Healing Escalation is a specific spell that does specific things, and its effects may not line up with the massive burst of generally healing/disease-purging radiance that Usagi used at the hospital in all cases.
It's not Samui I'm worried about telling. Her, as an individual, I would be willing to tell. However, we do have to keep in mind that MCAT is still a government agency, and Samui is its director. While I have some confidence Samui wouldn't tell anyone else thanks to how Naru's situation is being handled, even that makes me uncomfortable due to some of the people who have influence over her and the possibility of them trying to lean on her to get that information if it ever reaches a certain threshold of attention gained in their machinations. I'm also not "just" talking about the Diet when I say that either.
Yeah. We already know Fudo's poking around and at least beginning to send messages and interact with the Senshi directly (if only to make sure his son gets healed up ASAP). He's definitely going to be thinking of the Senshi as a power bloc he'd like to have a hold over, or a way to bribe us, or a way to neutralize us, or
something. And he seems likely to have a lot of access to information about MCAT's activities, to the point where even Samui might struggle to keep secrets from him indefinitely unless outside circumstances are making it easy for her to do so.
And that's just the most obvious example.
We can also just imply that Moon works as a fully adult school teacher. I mean, when she opened a company the first thing she did was create a school so...
The trouble is that "all the teachers at the school" is a fairly short list. If you've narrowed down Sailor Moon's identity to the point where you're seriously considering "is a teacher at this school," then it's a straightforward exercise in detective work to work your way down the list and try to select a specific teacher in particular.
And it probably won't take an Intrigue monster with a lot of resources (e.g. Fudo) very long to determine that
none of the teachers could fit the description, at which point he's going to start thinking about the possibility that maybe it's one of the student body. Someone with something like his own Symphogears.
Or we have Usagi say she was recruited by the Senshi to watch out for schemes targeting the school, and she reported it to Sailor Moon. I think Usagi is on record as working for Crystal Millennium, and Samui knows about Naru so it wouldn't surprise her that Naru's best friend is working for the Senshi. We could even tell the MCAT about the scouting of the Night Market that Naru and Usagi did together as a example of the work Usagi has done for the Senshi.
It could also cover for Usagi's improved test scores if she says she got interested in learning things when her magic was awakened, which has the bonus of being true, more or less. We just leave out the Senshi part, and it hangs together reasonably well.
The problem with repeatedly drawing MCAT's attention to the "Usagi Tsukino is heavily involved with Crystal Millennium and gets involved in shenanigans involving the Senshi" is that the more often we bring it up, the more likely the kind of bad actors we're worried about are to decide that Usagi Tsukino is a person of interest
in and of herself.
And Usagi's secret identity really wouldn't hold up well under truly close examination if someone were already investigating her seriously. She's been using casual teleportation too much.
Only really a problem if it's an object they can't just carry around with them though.
I mean it depends a lot.
The point is, I'm not sure that it's doing Mamoru a favor to put him in a situation where his physical body has some potentially complex and unpredictable blend of abilities and limitations that he didn't choose for himself, just to save some time and get him
into a body faster, when we may not be able to undo or fix or change things he's not happy with.
We can be reasonably confident that if we take a little time we can put Mamoru into a human body not too dissimilar from the one he had before the accident- maybe a child-sized body, maybe an adult body, but at least the same species. It would probably be more responsible to focus on that, if you ask me.
