Concur with you on the panning laws being a concern.
One of my colleagues had a recent premiere cc project he exported as individual surround stems (sourced from a pro-tools mix) same situation as me, but he had the sequence set up for Multi-channel, NOT the 5.1 option.
His levels came through, unmolested.
So I made a new sequence with those settings and now the audio is exporting
at the levels it should be (not being adjusted -6db on export)
here’s what the mixer looks like on that if helps anyone else.
