I don't think apple is too afraid of cannibalizing the Mac with iPad.
The iPad Pros are on par price-wise with the Mac after you get keyboard cases etc, and on iOS they also get a huge cut of every app sold since you have to get them from the app store. They'd probably be thrilled if Macs were replaced with iPad. The can always jack up the price later.
They wouldn't have spent years neglecting the downfall of the Mac if they cared so much about that revenue.
