I'm working from memory here, but I think that's going to be much hoppier than he wants, and I don't remember Peroni having any of that corn-like flavor from 6-row. The crystal malt wouldn't be typical for the style either. I'd go with something like 85% Pils, 15% flaked rice, and a single hop addition targeting 15-20 IBU. Just like any other macro lager.
What yeast are you going to use? That's probably going to make the biggest difference in getting you close.
