Wait! It was better when it was larger. At this point it seems a bit awkward, since it's half-hidden behind the engine. I tell you, when I run into a problem where I just can't get used to a certain part of a mesh, I take a step back and stop going about it the way I was. If you can't get it to work right for you, try a different approach. For instance, instead of two impulse drives, why not have one single long one at the rear of the saucer? Or perhaps having them hidden by the separation plane, so that the two engines mounted on the pylons are the only ones visible when it's integrated?
