Yes, qt4 don't have it.

It's indeed possible since nixpkgs did it:
<https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/qt-5/5.4/default.nix>

I think the tricks are at build time for qmake:
<https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/qt-5/5.4/setup-hook.sh>

And set QT_PLUGIN_PATH, QML2_IMPORT_PATH, etc. at runtime time.
