Twitter does public messaging and DMs, but is not a chat platform and doesn't have any of the other features of WeChat.
To become a SuperApp, X will need a lot of additional features: X will need enough features to both convince new users to join the platform AND keep them using it for most of their daily needs. That would mean Twitter would need to replace WhatsApp/Signal/Telegram when people want to chat with friends and businesses.
That would require a lot of new Twitter users! Twitter is noisy, but quite small for a social media.
Based on the track record of Twitter acquisition and subsequent changes, I don't see how Elon is going to massively increase the user base to have enough critical mass to make this happen.
Wechat is successful and became a de-facto "everything app" in great part because it's extremely useful to the Chinese government as a way to monitor and control its populace.
