Would it make sense to take a 777 run it out where they think it went and see if these "pings", data points, signals and see if they match via all of these magical formulas?
Probably not. First, the route it ran would not be the actual route of MH370. Second, for calibrating the BFO (which is the more problematic measurement) one would want to carry the actual SATCOM equipment onboard MH370 and be able to return 3-F1 to its original, eclipsing orbit and inclination. Neither is going to happen. The formulae have been tested on myriad other aircraft, so the basic equations are not in doubt.
