Maybe one already exists....??

Not sure what "higher authority" Paul set his info from (such as undocumented flags used in http://sqlblog.com/blogs/paul_white/archive/2010/07/31/inside-the-optimiser-constructing-a-plan-part-4.aspx) but it doesnt go beyond the realms of reason that there *could* be a "set good enough costs" flag somewhere considering you can mess with the optimizer to this degree.

This is all pure speculation on my part.
