If other settings are allowed, Pathfinder's is FULL of them: for example, Torag (LG god of dwarves, strategy and the forge) is drinking buddies with Cayden Cailean (CG god of alcohol, freedom and bravery). The LG Iomedae (goddess of valor, justice and rulership) considers the CG Milani (minor goddess of hope, devotion and uprisings) to be her "sister" as well (they had the same divine boss, the LN Aroden, before he died and Iomedae ascended to his place in the main pantheon).
