Good point! Still, I could swear I saw someone (@FakeUnicode?) do exactly this once, but of course I can’t find that tweet any more, partly because it turns out that search engines don’t handle ﷽ well at all, and I don’t feel like testing it on my own followers somehow.
Edit: it looks like it might count it as two characters, so that’s only 140 per tweet.
That’s definitely possible! @FakeUnicode mentioned in the discussion that, when 280-character tweets were first introduced in September 2017, it was possible to tweet 280 single-codepoint emoji using TweetDeck.

There are several amusing examples in the thread linked from this tweet.
