Option to default Hotkey for Camera Views to be more natural on numberpad

I would like to suggest an option to change the default hotkey for people who use the number pad. Today the hot keys for camera views at 3/4=front/back and 5/6=left/right. I understand that order if you are using the numbers at the top of the keyboard. But, if you use the number-pad to change views, it makes more sense for the Back hotkey to be #9. That would arrange the keys in a natural way which would make it easier to use.

Actually, now that I think about it, if you could somehow make both #4 and #9 be hotkeys for Camera View Back, that would work for both sets of numbers on a keyboard. That is clearly the better option but I assume might cause some weird duplicate code.
