Yes, you can indeed - except for the [-] which is hardcoded. Try the
following:

--8<---------------cut here---------------start------------->8---
#LATEX_HEADER: \setbox0=\hbox{\large$\square$}

#+BIND: org-export-latex-list-parameters (:cbon 
"[{\\parbox[][][c]{\\wd0}{\\large$\\boxtimes$}}]" :cboff 
"[{\\parbox[][][c]{\\wd0}{\\large$\\square$}}]")

* DONE Organize party [3/4]
       - [ ] call people
       - [X] order food
       - [-] think about what music to play
       - [X] talk to the neighbors
--8<---------------cut here---------------end--------------->8---

So the question is: why is the [-] hardcoded?
