I see some superset tools that extends Markdown, like Quarkdown seems to be very powerful. Is there a way to replace markdown-it extension with tools like Quarkdown?

No not possible, you would need to extend markdown.it with the various features you want.

GitHub repo of the day, impressive!

QuarkdownはMarkdownの代わりになり得るか
