Hello, When you use mBJ (number 28 in case.in0), the total energy is calculated with LDA (i.e., the mBJ orbitals and electron density are plugged into the LDA functional), and you can use this total energy for calculation of energy vs. volume of unit cell. What is not possible, is to use forces for the optimization of internal parameters. What do you mean by QW, QWR, QD?
Hybrid functionals similar to HSE are in WIEN2k, but I don't know when it will be released into the distributed WIEN2k version: http://arxiv.org/abs/1103.4466 F.
