How have you got on?
The glass appears to be the digitizer at least it seems to be fused. The LCD is glued to the pannel and has different cables.
Your method may work and it is worth the gamble given it is considerably less costly than any other solution. You will loose accuracy because of refraction.
Finding a replacment of correct model appear impossible. Versions sold as replacments ebay and elsewhere do not have coresponding numbers or connectors at least to the model I have and I am told models other than 1.1 are rare.
I suggest contacting microsoft for repair or wait until a Digitizer + LCD becomes available.
Seperating the digitizer from the lcd is extremply hard because of the glue used. I tried and tor the lcd coating.
Good luck.
