I was thinking of material other than notebook that ought to be in many IPynb.
Skimmed too fast.
I concurred with brian for the "One ipynb to rule them all" and produce multiple documents.

Yes it is do-able (not sure if it is supported), I was more concerned of storing the "answer"
into the metadata, ability to get back to *initial* value of a cell.

Something along

CodeCell.prototype.old_execute = CodeCell.prototype.execute

CodeCell.prototype.execute = function () {
        if ( ! this.get_text().match('_{4,}') ){
            this.old_execute(arguments); // not sure of the unpacking of arguments here, might be [arguments]
        } else {
           // hire a GSoC student to write the code that will highlight the ____ in red.

wrap in a IIFE, listen for the correct even in custom.js and load with require()
