Play him in the middle and Bruno on the right.
Not ideal, but it could work well-ish. Or - to put it like this: if Bruno can contribute significantly if somewhat erratically from out wide, he's actually our best alternative in that position by some distance.
And it's arguably more important to have more of a "system player" in the middle, as part of a midfield configuration.
Put it like this: I prefer a functional if not optimal Bruno on the right (in, let's say, a "freer" role - although Bruno is more than capable of doing the actual leg work/pressing and so forth too) and Mount as a central AM to the alternative, which seems to be: Bruno as the central AM and...yes, who on the right?
