Since you ask, I am wondering if the Emulator II waveforms have been included in any of the existing Sound ROMS. If so, it might just be a matter of creating presets for them to approximate the Emulator II.
Of course, if the waveforms can be loaded into an Ultra Sampler, they could be burned to a flash ROM.
Maybe someone here is familiar with the Emulator II samples and already has them in an *.e4b file.
