Could you build this?

Partial Browser PDF viewing, highlighting, signing, and page reordering are doable with existing libraries, but true in-place text editing of existing PDFs is hard because the text layer is not structured for editing.

What it would actually take: Build a web app using pdf.js for rendering and pdf-lib for writing, with a canvas or overlay layer for annotations. The hard part is editing existing text and reflowing content in arbitrary PDFs, which requires parsing font and content streams and handling font substitution. That needs a developer with PDF internals experience.
