The servo cutouts in the MX2 are perfectly sized for the S3114's, which are only very slightly larger than the S185. As Seth and Dave said, if you want to go with S185's, I would suggest two of them.
I need to weigh the new plane, but I'm guessing it's right around 5 ounces. Whatever it is seems perfect... the printed kit with stock setup is at a really good weight for a balance of inertia for 3D and floatiness for slow stuff.
