Thanks for the comments - I'd often thought this was a good idea but then.. So perhaps an issue is the distinction between a shopping mall and a shopping centre. Malls have "exterior" windows on the inside overlooking public spaces. Is that sufficient? And also, a place is not a slum while it is desirable, and perhaps the conversion process needs to start when a mall is still a popular destination. Sheffield's Medowhall is a place I'd love an small flat, but the rental per square meter would not allow anything residential ATM.
