Iphone 4s Replacement Screen?

Can I replace a iPhone 4s screen with a iphone 4 screen? And the power button and the volume buttons too?

"The connectors are the same for the digitizer and LCD and the screen will function properly between the models but the parts are physically different and will not fit either way. The sensor layout is also different which would cause the phone to not work properly. The home button is also different.
In short, you can't do it."

As for the power button and volume rocker, those are identical between the 4 and 4s
