The aircraft would be reconfigured into the standard Aer Lingus layout, with the Aer Lingus hard product. Air Tanker did the same when they leased their aircraft to Jet2 - their A330s all had Jet2's grey and red seating. Also, Thomas Cook's Air Tanker A330 was in fact reconfigured into standard Thomas Cook layout, with Zodiac Rave seat back IFE installed, so your comments regarding the matter are incorrect.
