With knowledge of V2 speed and runway length combined with aircraft position, you could do calculate somewhat of a minimum of acceleration required.
If that goes below the required acceleration between 40 and 80 knots (groundspeed acceleration, this system isn't for wind shear), give a warning which should produce an abort.
Even with a wrong gross weight and somewhat lower V2 input, the system would likely still catch cases where planes rotate with all engines operating scrape the approach lights.
You could get even more tricky and infer gross weight from actual acceleration given a certain EPR.
That gross weight gives you an V2 to use for the computations.
