Remember the Voyager had wingtip damage at take-off. They
did some maneuvers to break their winglets off.

A few years ago a 707 had an engine fire and melted about
half a wing off the airplane.

A vertical winglet would be easily compensated with rudder


The winglets on the Voyager were much smaller in size both compared to
the wingspan and absolute size. The 737-800 winglets are very tall (8
to 10 feet) and fairly large in comparison to the rudder size and
wingspan.

You may be right that the rudder could compensate, but I could also be
convinced that the rudder wouldn't be enough to do it.
