Hi

NLCC with meta- or hybrid-functionals is not well defined.
I strongly advice against using it without further development.

1) you can. However, I would only do it for "similar" functionals. 
   The only problem you can run into, is a reduction of accuracy. 


Does this also correspond to NLCC pseudopotentials? Can we use NLCC-PBE pseudopotentials for computations with e.g. TPSS or PBE0 functionals?
