How about some MSLPTCPMBP? (M/S linear phase time compensated parallel multi band processing)
Try playing with the X-over control in the multiband. If monitoring is up to scratch, you'll find the Xover to impart a strange distortion wherever it lands. Sometimes once in the fullmoon it's just the ticket. Most times it's a question if finding an area where the Xover does the least harm.
Most of the time multibands are off. Unless they're needed.
Try starting with one band, perhaps two, but as a general starting point, there's no need to run the full mix through a Xover network.
(to adresss a typical concern: it's probably linear phase and that nulls, though only when there's no processing. the Xover is funny when there's processing going on. the linear phase filters create artifacts in themselves too).
