I'm wondering if a stereo to 5.0/1 upmix followed by a matrix decode/synthesize (to Atmos like 7.1.4, maybe using the new definition of Dolby Surround) has been tried and what was the result, is there enough out of phase content in the 2.0 > 5.0/1 upmix to be usable for additional matrix decoding/synthesizing to get more than 5.0/1 channels?
