One that's never been done before!
We have SEM's with added polyphony but exactly 0 Oberheim 8-Voices. They made more than one product and this is probably one of the cooler ones and most rare. It's not another OB-Xa or single voice SEM.
If someone did another Minimoog or OB-X or Jupiter-8, I'd get it. But Moog, Oberheim and Roland still made lots of synths we don't have models of. If you don't have any interest in any of them, then just stick to dozens of other products that certainly do something you're more interested in...
