I beg to question, if the Airtab design was scaled down to work on a car such as my xA would it give us a noticeable result?

I see no reason why they wouldn't work when scaled down.
Work as in "creating vortices" that is, wether they actively reduce your total drag is something else again.
If you look at ZZ-tape or dimple tape for gliders, these are only 0.4 to 0.8mm thick, that's 1/6 to 1/3 of an inch, and they work.
Airtabs are obviously truck-sized, though MetroMPG has shown them to be smoothing out the airflow on smaller cars - though no verifiable overall drag reduction / MPG increase was noted.
