Macro, aperture & sharpness question

Having read Ian's article on diffraction softening at smaller apertures I have been trying to keep to f8 or wider. The problem obviously comes when trying to get decent DOF for macro subjects where smaller apertures are required.

Say I take a picture using an 50mm lens so the subject fills the frame. If I then attach an EC14 and frame the subject the same then am I correct in thinking that, because I am further from the subject, the DOF will be greater?

Are there any other suggestions on this?
