I think it would be psychologically better to train your mind to adapt to different controls quickly. I play a lot of 1st person shooters and I can use my mouse with the y axis inverted like an aircraft's joystick or not. I can also use the arrow keys or wasd. I can also reach for all the varied reload, crouch and crawl buttons for different games with ease. When I am at a friends house or playing on someone's console I adapt very quickly to the controls and I don't have to insist that they change the settings over and over.

You'll be better off that way.
