If you're talking about an IBD analysis of sharing within the Italian peninsula it's already been done by Fiorito. Unfortunately I don't see Campania listed on the spreadsheet.

If you're talking about gedmatch Admixture results based on calculators like Eurogenes K15, I highly doubt academics are going to do it, and whatever amateur posters would come up with would be questionable given that they wouldn't be using scientifically selected and vetted random samples.
