They could've continued with the Spice Girls brand if Sporty was on board too (since they've gone on as quartet before). Although Posh was my favourite (along with Scary Spice), she really brought nothing to the table vocal-wise and was the only member that couldn't achieve a number 1 outside the group. That being said, she's arguably the most successful of the girls and honestly it would probably be backwards movement for her career in fashion if she went back.
