By this stage our test setup should be on an engine dyno.

I presume that the higher (or lower) than Nyquest frequency would result in a type of "multi-scan" type sensor strategy taking samples at discernible crank angles that would later be compiled into a high resolution chart based on several crank turns worth of samples?

The presumption, of course, is that the engine operation is constant during the crank turns whose samples are utilized and that can only realistically be approximated with an engine dyno.

IF that is true, then the actual cost of obtaining equipment for these types of measurements could likely be significantly higher. What about subcontracting to a firm that already has the lab and sensors? Does FSR have access to such a lab?
I have an engine dyno no sensors of those types thou.
