Not yet. I have just tried this option, but it gave me some strange 
results, which I think can be boiled down to the following example:

\documentclass{article}
\usepackage[displaymath,counters]{preview}

\begin{document}
\begin{equation}
  \label{eq:1}
  a=b
\end{equation}
\begin{equation}
  \label{eq:2}
  b=c
\end{equation}
\end{document}

If I generate previews for this buffer I get, as expected:

  a=b  (1)
  b=c  (2)

However, if I then regenerate the second preview, I get

  b=c  (1)

there. If I regenerate the first preview (starting from a consistent 
state) I get

  a=b  (2)

Is that expected? Am I doing something wrong?

Strange, I don't see any difference. LaTeX-command-style is

(("" "%(PDF)%(latex) %S%(PDFout)"))

And TeX-expand-list indeed contains

 ("%l"
  (lambda nil
    (TeX-style-check LaTeX-command-style)))
[...]
 ("%(latex)"
  (lambda nil
    (if TeX-Omega-mode LaTeX-Omega-command LaTeX-command)))

BTW, preview-LaTeX-command's value is

("%l \"\\nonstopmode\\nofiles\\PassOptionsToPackage{"
 ("," . preview-required-option-list)
 "}{preview}\\AtBeginDocument{\\ifx\\ifPreview\\undefined" 
preview-default-preamble "\\fi}\\input{%t}\"")

I guess you would have protested if I had been wrong with stating that 
preview-latex gets the command to run from LaTeX-command-style...
