You can rescale MaxDiff utilities easily enough if you want to, but that doesn't make them ratings.
For example, you might take the lowest MaxDiff score for a respondent (say it's a -4) and the highest (say it's a +5.3). Now, just divide that range into tenths, so that you have the range -4 to -3.07, -3.071 to -2.14 and so on to 4.37 to 5.3. Now just put the respondent's MaxDiff scores into those range-buckets and you have a 1-10 rescaling of the items' utilities.
No doubt there are other ways to do a 1-10 rescaling, but again, I'd be hesitant to call any of them "ratings."
