Would you get the same correction with a refractor by taking the diagonal
and setting a set screw at one end to slightly tilt the mirror so as to
have the same effect as slightly tilting the eyepiece?

No, you are merely changing the reflection angle or the overall location of
the focal plane.  You are not unduing atmospheric or chromatic dispersion.
