Problem is, that isn't likely to happen. Our problems in midfield aren't just personnel available. It's the actual setup.
EtH considers Casemiro, Amrabat and Mainoo our 6s. That's why, when fit and available, Casemiro and Amrabat didn't play together, and why Amrabat and Mainoo don't now. It's always one of them with Bruno and then one of Eriksen, Mount or McTominay.
For it to happen, we'd need ten Hag to admit his setup is wrong and change, but he's a very stubborn person. We heard that before he joined from Ajax fans in that, once he has his mind set on a specific system, he won't change it. And, even with Casemiro and Mount unavailable for the majority of the season, he's shown that here. We've still set our midfield up the same way he intended to do with Casemiro, Mount and Bruno regardless of personnel available. One 6 next to a really attacking 8 and a 10.
