Having said that, your "statistical wind" certainly doesn't cope with several base turn procedures that I know
The use of the omni directional wind or the stastical wind as far as I am aware is not to make it easy to join the inbound easily in a large crosswind as described. I believe that the wind is used to calculate the shape and size of the protected area that one could drift into should one pass through the final approach track.
The outbound track must be tracked as accurately as possible.
This whole argument about tracking outbound in a severe crosswind is the exact same as doing say an NDB/DME base turn when there is say a 50Kt tailwind on final approach........would anyone seriously considder exceeding the outbound DME to provide suficient time to descend on final approach to circling minima?
