You are right - org-preview-latex-fragment is independent of the latex
exporter.  The preview latex header is constructed (in
org.el:org-create-formula-image) like this:


,----
|     (with-temp-file texfile
|       (insert (org-splice-latex-header
| 	       org-format-latex-header
| 	       org-export-latex-default-packages-alist
| 	       org-export-latex-packages-alist t
| 	       org-format-latex-header-extra))
|       (insert "\n\\begin{document}\n" string "\n\\end{document}\n")
|       ...
`----

so you might want to experiment with the variable
org-format-latex-header-extra (and maybe some of the others as well).

Certainly far from simple: but if your trial-and-error succeed, then you
might be able to propose a simpler mechanism.  Let us know.
