I think you can preview \ce{...} just fine, with appropriate LaTeX
headers.

This should not be possible. Org cannot recognize all LaTeX syntax. If
you cannot preview it, Org does not understand it. IOW, it would be
a poor experience if you preview something that doesn't exist, e.g.,
upon exporting the document.

OTOH, nothing prevents an external library to allow previewing any LaTeX
code (probably re-using AucTeX facilities).
