If I had Shimano type hubs I might try making shims out of shim stock and sliding them in the gap when installing the cassette. Glad I use Campy, so this is not an issue .
Thanks to 11spd cross-compatibility, using a Campagnolo freehub and gear cluster to replace, or instead of, Shimano units is a totally legit way to solve the problem. Campy 11spd gears work perfectly under Shimano 11spd derailleurs, as do Shimano 11spd cassettes work great under Shimano derailleurs.
