The new hot rumor seems to be that BKN will use Russell in a S&T for AD, but this seems to be far from a given. First, Russell would have to agree to go to NOP - and with so many teams having cap space, it seems he may have other suitors and he could choose his destination. And, of course, if the Nets matched, he isn't going anywhere.
And, second, this also assumes that the Pelicans would prefer Russell to Tatum, which seems far from a certainty.
I don't see it as 'impossible', but it falls right in line with all of the other Terry Rozier S&Ts we see here. They just don't occur very often.
