I suppose it's theoretically possible, but you would need the 30b's ROM code, which Marcus von Cube states is HP's intellectual property.

Well protected IP I must say. You can load the image in an HP 20b but it will stay an HP 20b. The 30b functions are not available. I assume there is some hidden trick to identify the actual hardware and disable certain features depending on it.
