Narrative:

We were ILS to both 4's; departing 4L. Local 2 departed a B757; which was off the departure end of 4R by the time aircraft X was short final and began his missed approach. I was not confident in the performance of the widebody to make a tight enough turn and thought that the planes would end up closer together; so I kept him on runway heading and as soon as I saw aircraft Y was through 2;000 cleared him to that altitude. We had over 30 degrees divergence; 850 ft and increasing of altitude separation but the super had to fly through the flight path of the B757.this set up is difficult due to the flight path of the 4L departure crossing 4R departure end.
