You can recreate the presets from electrical measurements, however I would NOT convert each channel to linear-phase. The phase differences between channels in the multi-way are part of the preset and are inherent in making the preset work. If you change these relationships, you could dramatically alter the system’s response and directivity in and around the crossover region.
As for making the combined acoustic response linear-phase, in addition to electrical measurements of the preset, you would need some reliable or meaningful acoustic measurements.
