I have the following which, although it does not do what you want, it
may give you some pointers:

#+begin_src emacs-lisp
  (defun org-latex-format-inlinetask (todo type priority name tags contents=
 info)
    "Format an inline task element for LaTeX export."
    (let ((theinlinetask (concat todo " " name "\n\n\\noindent " contents))=
)
      (if (and todo (not (equal todo "NOTE")))
          (format "\\footnote{%s}\\marginpar{\\fbox{\\tiny\\thefootnote. %s=
}}" theinlinetask todo)
        (format "\\hl{%s}" contents))))
  (setq org-latex-format-inlinetask-function 'org-latex-format-inlinetask)
#+end_src

You can trim this down and replace the \\hl{%s} with, for instance, an
mdframed environment which allows you to control the width easily.

I will add that, for a number of reasons including advice from this
list, I have moved away from inline tasks almost completely and now use
drawers instead.
