I absolutely love it that you can import mermaid. I love mermaid because I'm a huge fan of anything related to code that can I check into git, track its evolution and the thinking that went behind it.

However, those who don't know mermaid have to struggle with updating my diagrams. Your approach, atleast in theory, should get us the best of both worlds. Mermaid for those who would like to and the mouse for those who don't.

This also addresses the issue that large complex diagrams can get unwieldy using Mermaid and moving things around with a mouse would fix those edge cases.
