Illustrator :: CS6 - Publishing PDF From Word Document Full Of Diagrams

I need publishing a PDF from a Word document full of diagrams created with Adobe Illustrator CS6. My diagrams are all vector. I am free to export them anyway I like. My Word doc has many cross-references, footnotes and Endnote references and a large table of contents. It is a few hundred pages long, with around 50 diagrams. I would like to preserve the original quality of the vector art and the intra-document clickable links.
 
Each step in the process has multiple possible paths, and each path often many options. There are 3 steps:
 
1) Export from Illustrator  to: .ai, .pdf, .eps, .wmf, .emf
          optional 1b) Convert (eg. use Acrobat to convert .ai to .doc, .eps or .ps)

2) Import to Word: drap and drop, file cut and paste,  insert picture, insert object, insert object linked to file, PDF Reflow (Word 2013). I tried them all.

3) Publish to PDF from Word. Many different paths...
  - Print to PDF:  I have AdobePDF, PDFCreator, NovaPDF printers installed
  - Save as... : Save as->AdobePDF or Save as->PDF or XPS
  - Plugin toolbars: Acrobat->CreatePDF, NovaPDF->Save as PDF, PDF Architect->Convert
or
  - Save as .doc and convert with Adobe Acrobat.
 
I have tried many different permutations. There are 4 possible errors:
E1 - The diagrams are converted into bitmaps.
E2 - The diagrams are 'linearised' - curves are converted into chains of linear sections
E3 - The diagrams are corrupted - text missing, characters changed, dotted lines become solid lines etc.
E4 - Hyperlinks are lost.
 
Here are some results of my tests.
I see no difference so far between Word 2007 and Word 2013. Results below stand for both.There is no difference between Word->Acrobat->CreatePDF and Acrobat->Convert Word to PDF.Illustrator -> AI -> Acrobat -> Word almost works, but diagrams are corrupted in various ways (eg. dashed lines become solid).When export from Illustrator as EPS level 2, EPS level 3, EMF, WMF and PDF and get different results depending on the path to PDF: 

No links preserved:
Word->Print to AdobePDF:    Good: eps2, eps3, emf    Bad: PDF (E1), wmf (E2)
Word->Print to PDFArchitect: Good: eps2, eps3, emf    Bad: PDF (E1), wmf (E2)
Word->Print to PDFCreator:  Good: eps2, eps3, emf    Bad: PDF (E1), wmf (E2)
Word->Print to NovaPDF:      Good: -  Bad: eps2 (E2), eps3 (E2/E3), emf (E3), PDF (E1), wmf (E2)
Word->Toolbar->PDFArchitect: Simply prints with current postscript printer. One of above.
 
Links preserved:
Word->Save as AdobePDF:  Good: -  Bad: eps2 (E2), eps3 (E2/E3), emf (E3), PDF (E1), wmf (E2)
Word->Save as PDForXPS:  Good: -  Bad: eps2 (E2), eps3 (E2/E3), emf (E1), PDF (E1), wmf (E2)
Word->Toolbar->Acrobat:    Good: -  Bad: eps2 (E2), eps3 (E2/E3), emf (E3), PDF (E1), wmf (E2)
Word->Toolbar->NovaPDF:  Good: -  Bad: eps2 (E2), eps3 (E2/E3), emf (E3), PDF(E1)
 
So, only the "Word->Print to PDF" pathways provide good quality vector diagrams, but none of these preserve intra-document links.

I have:
- Adobe Creative Cloud CS6 (Illustrator, Acrobat etc. all latest versions)
- Word 2007 (latest version (SP3 12.0.6683.5002))
- Word 2013 (Office 365 latest version)
- Access to a Mac with Word 2011.
