Folks, thank you once again for all your great tips - #GravCMS ft. #Gantry framework look like to be my choice.
Actually, I am already migrating the stuff there. It seems to be exactly what I wanted.

Depending on your needs, #GravCMS may be something to look at. There's a #drupal7 exporter to #GravCMS, too (disclosure, I wrote the exporter a while back)
