Nice and for the A321neos registrations these might be a continuation of the A321-211WL fleet B-162xx basically taking a page from PAL Philippine airlines registrations for A321ceo and A321neos. For BR Rival PR the A321ceos went RP-C9901-9929 and A321neos are RP-C9930-9938. If BR went this way then A321ceos B-16201-16227 this includes Sanrio jet paints B-16205 Gudetama B-16207 Fifi B-16217 Pink paint. leaving the A321neos as B-16228 and up. For the A350s can they be like B-165xx or use the remaining B-163xx which were the A330s registrations
