There is already a port of sd2iec to the Mega2560 hardware. Feature-wise, it would be years ahead of this and I believe there is already code to do IEEE-488.

Do you know if someone has designed a shield for it already?

No idea at all. In fact I had no idea what you meant with “shield”. Now I know that a shield is a daughterboard that fits on the original Arduinoe (or Pi).

I'm thinking it should include ...

Not knowing how the schematic looked like, I had to download and install Kicad first. I created a PNG of the schematic and if interested, ask me. 

First I haven't any knowledge of the Mega2560 at all so I have no idea how the various pins behave: totem pole, OC or something else? What they can drive? Can at least one be used as interrupt input? So that are things I have to learn first. And that will cost time which I don't have very much ☹

I would certainly include an ATN trap. And why not adding an IEC bus? If possible parallel to the IEEE one. A small LCD screen + some buttons?
