That's what indirect buffers do. Maybe the indirect buffer
functionality could be beefed up to support what you want?

> The text of the indirect buffer is always identical to the text of its base buffer; changes made by editing either one are visible immediately in the other. But in all other respects, the indirect buffer and its base buffer are completely separate. They can have different names, different values of point, different narrowing, different markers, different major modes, and different local variables.

BTW what's the purpose of lentic-mode then? To be "providing multiple persistent views"?
