Depends on what you want your buggy to do. That will make it wheelie a lot more and put more strain on the rear portion of the drivetrain as a result but you won't unload the front wheels under lots of power. That will probably make it push (oversteer) in the corners, so if you're racing it you'll want to keep the center diff. Personally, I'd just keep the center diff and put thicker fluid in it to adjust the unloading unless it is strictly an onroad buggy and you want it locked but lighter weight than a locked diff.
