Finally we do intend to follow industry standard ESD protocol as part of the shotgun approach.

Interference is no longer an ESD problem.
Also, a wire that isn't terminated at one end isn't likely to result in much inductive coupling, and it will be much, much less than a wire that's terminated at both ends. Having it terminated at only one end will make inductive coupling almost disappear. There's no effective loop area if you don't have a loop!
You may have parasitic capacitive coupling though.
