Multi page growing form

I loved LiveCycle.  It allowed me to do this:


Now, because XFA never grew and was discontinued, I need to create this functionality in Acrobat forms. 
I realize that Acroforms does not have growing fields, but I really am at a loss here.  I need to figure out a way to allow users to create a page 2 (3,4, etc), while putting the signature fields at the end.   This text may be copied/pasted from another application into this form.  When the user is done, they will "print to PDF," flattening the document into a multi-page PDF document.  

I am looking for suggestions.  I am pretty good with the javascript, familiar with the use of hidden templates, and have a pretty good understanding of Acrobat form.  This is why I am discouraged by the number of "can't be done" comments.   I have come close with using the fieldFull event, but it seems to be a bit flakey.  The event.change and changeex  doesn't give me accurate data about what was cropped out.

I would really love to collaborate with someone so we can give a REAL answer to people.  I see lots of people asking this question, some "almost" answers, and LOTS of "it can't be done." 

Help?
