That would be like Ben Spies and Haga wild carding in a AMA race who cares. They are WSBK riders dropping down in competition to race BSB. Morias had a good ride going at Kylami so he has a little experience on the 10R this year. I am sure Hacking would be just as fast at Brands.
I know I'm biased on this topic, I know Shez personally, but he is talented. At one of our Track-Daze events at Phakisa he was 3 seconds off Rossi's best lap there on the 990 M1. Shez was riding a ZX-10R in Superstock trim, ie std motor with pipe, filter and PowerCommander, Ohlins fork internals, Ohlins/Penske shock (they were testing both), treaded tires, braided hoses, 520 chain conversion and race fibreglass bodywork. Std wheels, brakes, swingarm etc etc.
