Im Unity 2D selbst zur Ubuntu 12.04 gibt es immer noch keine Möglichkeit, die Icon Size im Launcher zu ändern. Ein Post auf ubuntuforums.org beschäftigt sich mit einem Skript, dass die Iconsize (systemweit) ändert

Dieses Skript habe ich z.B. auf meinen TS als /root/unit2d-iconsize.py abgespeichert

Alternative zu Fuß:

Hier ein Post in Google+, der sich damit beschäftigt, über ein paar Hacks an Systemdateien die Einstellungen (fest) auf eine hübschere Größe zu setzen:
