The BBC would be absolutely mental if it didn't hire the same team to create a new identity for BBC 1 and to have it tied in to BBC 2's to create a flow and some network familiarity. Same for BBC 4.
That would give each channel more consistency too.
Hopefully if they do hire Superunion (knowing that they will due to the success of the BBC2 rebrand), they'll give BBC One a new look and maybe a new logo. They haven't had a new logo to call their own since 2006 and it's in dire need of a dramatic change.
Same for Four, they've had the same black box since launch back in 2002.
