Yes, that also would work.
The gtk.css file placed in ~/.config/gtk-3.0 gets First Priority.
Then, the gtk.css file placed in either ~/.themes or ~/.local/share/themes gets next priority.
That is partly why I prefer edits to be made to ~/.config/gtk-3.0/gtk.css while the other reason is because edits are more easily altered or undone in ~/.config/gtk-3.0/gtk.css than they are in the Main Theme. What if you do not remember the Original parameters of the Original Theme, but it is already changed and saved?
