Square Wave Voltage Level Shifting
You do not need or want the intermediate voltage represented by V3.Trying to create it as an actual volateg will cause you effort which is not required. 

Allow the low side driver to drive a high side driver connected to tje V+ rail.

THEN limit the swing of the high side driver OR the swing that the FET gate sees. Zener diodes are your friends in such cases.

Note that you should zener clamp the INPUT of a driver stage, not the output - so that the driver is not always "fighting" the zener.
