Why? I feel the more “accessible” 8 track products are usually good enough these days and it isn’t the aim of them to go up against 8 channels of Prism/weiss/Burl or whatever. And those high end convertors are often used in places where everything is at least very good to among the best (whatever that means), including the room and the operator(s) of the equipment.
Most of the rest of the chain would be a weaker link to producing a track including the person writing it, than some of the modern mutlitrack recorders.
I would focus instead on usability.
