I agree. He gets toned down quite a bit... But I'd bring it back. Haha.

If you actually want to do this...I mean first of all yes, why? But why not go whole hog?  Ensure that Hal has an Inuit mechanic he refuses to learn the name of and refers to only as 'Pieface' because of Eskimo Pie desserts. Make sure he insists Wonder Woman is just their secretary and doesn't do anything combat related. Have him insist we're at war with the 'Nips and that the only good one is a dead one. 

Hell, as long as we're at it have Batman still occasionally put a Robin over his knee and spank them and sleep in the same bed as his wards. If we're going all the way back, have him still use a pair of guns.

These are anachronistic elements of characters from a time involving wildly different standards and characterization. I don't see why you'd want them, but there ya go. XD
