You can even change the unconfigurable lxterminal from lubuntu to use OS X keybindings. Run apt-get source lxterminal. Then change the bindings in src/lxterminal.h (change <CTRL><SHIFT>C to <ALT>C and the same change for V, for paste). Then run apt-source --commit to commit your change locally and finally dpkg-buildpackage -us -uc to build your modified lxterminal.

Edit. And change other keybindings in .config/openbox/lubuntu-rc.xml. For instance change keybind key="C-Left" for GoToDesktop left to get the same binding as in OS X.
