Though maybe it wouldve choked her with her bigger body and all. Earth 16's shapeshifting (or at least the Martian version; Clayface doesn't seem to work this way) is only required to change shape, not maintain it. So if the ability is taken away the shapeshifter is stuck in their current form, whether or not it is their true one.

Hmm that would make sense, but someone in Ask Greg asked:

"Why did M'gann revert to her white martian form when confronting J'onn in Auld Acquaintance? It seemed unnecessary."

To which he replied:

"It freed up her entire focus on the psychic. She's more powerful in that form."

This suggests that it does take up a part of her focus to maintain her human form, Though this refers to her before the timeskip, so maybe she just got more power to the point where she doesn't have to focus on her form at all? Well this is just a little nitpick of mine, so its not a big deal. I can totally see that she is just really used to the green Megan form after using it for so long.
