Ehhh the Sens aren't really going to be interested in the switch from Brown to Mittelstadt. Brown's currently transitioning his game to the NHL level; call back when Casey is dominating at the AHL level and then maybe they're at equal footing. It's at best no better than an equal switch where the Sens are instead going to stick with the bigger body in Brown, but when you look at it it's clear that Brown's just the better prospect.
