What do you find shady about moving away from the consumer welfare standard, Khan herself aside? In my view, returning from a Borkian era back towards something more Brandeisian makes a lot of sense. "Consumer welfare" to me feels like it assumes a functioning free market system, but antitrust should deal with powerful entities that are already able to distort "free" market functioning by their size and power. But, I'm politically an anarchist so of course I would have a "big is bad" bias.
