QR reparameterization, non-centered parameterization, hierarchical model

Hello, is it possible to use QR reparameterization in a hierarchical model? How does it work with random slopes, especially with using non-centered parameterization? Any insight would be much appreciated.

There is a thread here QR Decomposition in hierarchical models
and here QR decomposition of parameters for multilevel regression? do those help get you started?
