Magnify entire dock instead of where the cursor is?
Yes and no.

You could get most of the functionality by:


Turn Hiding on - you now need to mouse over to grow it.
Turn Magnification off - since all the dock needs to be the same size
Making the dock super large when it's visible - so when you mouse to it, it's zoomed to your preference.


No, in that you can't have a small bit of the dock on screen and then have that visible dock get larger when your cursor is on it.
