Since you asked. With AD Model Builders Random Effects module
it is possible to declare any of the parameters which might be
considered fixed effects to be random effects so that they are
"integrated over". I did some simulations work with this
with nonlinear fisheries management models far more difficult that what
lmer can deal with and found that the procedure worked quite well.
I can discuss this with you off off list if you are interested.
