I'd suggest that the biggest factor which breaks (brakes?
) the relationship between approach speed and landing distance is going to be altitude, unless you express approach speed in terms of TAS, not IAS.
That aside, here are some numbers for sea level, ISA, calm conditions:
80,000lb aircraft : Vref=132kts, ALD 2680ft
38,000lb aircraft : Vref=132kts, ALD=2830ft
38,000lb aircraft : Vref=132kts, ALD=2800ft (not the same aircraft as #2, not even common wings, brakes or engines)
