Playing him DM would be like making him play with the handbrake on in my opionion. If his passing and touch were better it might be worth it given his energy levels, but they're not.
I'd just let him off the leash to go and cause as much mayhem as possible.
Where have you got this idea that defensive midfielders are restrained? There job is to go and cause mayhem. One of the two other midfielders would have to cover for him when he goes into full headcase mode of course, but Anderson and Cleverley are certainly capable of that between them.
