Did the proposal of McWhopper create consumer confusion?

There's buzz about the BK proposal to create a
McWhopper, if only for a day.

Implicit is the idea it would be a
Hybrid of a Whopper and a Big Mac, which
Inherently are different products.
Such an item would cause consumer confusion.

A bit of brand trivia. The original name
for Gerry and the Pacemakers was
Gerry and the Mars Bars. The latter
did not happen.


For some of the details:
