I'm curious and wondered why AC has so few aircraft in the (rather unattractive) *A livery.

Is there a minimum requirement for AC to have a certain percentage (I've read 5%?) of their fleet in the *A livery?

Why are none of the 77W's/77L's in that livery? An E-Jet would also be quite stunning in that scheme...

Why doesn't AC keep their house colours on the engine cowlings/winglets, like other *A carriers? Also interesting to note that the typeface for the titles "AIR CANADA" on the *A birds is from the old logo...

A quick search on Airliners.net has found the following:
