I don't think there is an easy solution. The least difficult
way to go is probably to program your own random effects
version of box-cox using maximum simulated likelihood, as
discussed in this special issue of the Stata Journal:
http://www.stata-journal.com/sj6-2.html
However, I think that that would still be more trouble than
it is worth.
Hope this helps,
