The method described below can of course accomplish this: you need to
change the :ostart and :oend settings. It's also fairly easy to define
customizable variables for all of this, but that is left as an exercise
to the interested reader... Nicolas might be interested in anything you
come up with.

Hint (entirely untested):

(defcustom o-e-l-l-s-ostart "\begin{enumerate}\n" ...)
(defcustom o-e-l-l-s-oend ...)
...

(setq org-export-latex-list-settings `(:splice nil :ostart ,o-e-l-l-s-ostart :oend ,o-e-l-l-s-oend
                                                   :ustart .....)

...[ some way to reevaluate the above variable if any of its components change - does custom provide anything like that?? ]...

(defun org-list-to-latex (...)
   ...
   (org-combine-plists
        org-export-latex-list-settings
        params)
   ...
