Yes, there have been several comparisons of Rasch measures and physical
measures. Here are two:

http://www.rasch.org/rmt/rmt112a.htm - physical weight
But would be delighted if you would conduct your height experiment and tell
us about it.
I'd love to see what happens. Pairing persons heights in cm and their Rasch
heights simultaneously on a vertical line and comparing the calibrations
give a good test of Rasch's interval scaling, I guess.
