That transformation trick really only works for multivariate normal,
although there is a similar trick for multivariate t.  For other
distributions there are other tricks which
you can find in texts on this subject.  But, there is a general solution

for most of these problems:  Gibbs sampling.  However, I haven't
seen an implementation of that in Mathematica, but I am interested
on working on it.
