What do you mean by hierarchical EFA? If you mean higher order factor analysis, i.e., imposing a factor structure on the factor covariance matrix, I suspect the answer is not at the present time. You could always extract the factor correlation matrix from an oblique rotation and work with the Schmid-Leiman transformations yourself.
However, for a confirmatory model I suspect you could set this up in -gllamm- but I'd sure want to test it carefully on examples that I was certain about. I believe there are some examples of this in the PROC CALIS documentation in SAS/Stat, for instance.... Just checked. It's a replicated example of some data from Thurstone from R. P. McDonald (1985), Factor Analysis and Related Methods, LEA, , p.57, p.105.
