Keep the ADS as a size 1 internal with all the details but make the grey blob scanner mounted on a utility slot (because the internal slot is for all the computers doing post processing on the raw scanner data to colour in the blobs).
You can take the utility mounted one if (a) you really want to explore like that or (b) you're in a small ship and want to sacrifice super scanner so you don't have to pick two from shield/AFMU/hangar...
