Make your new gimmick look shytty so they let you use your old one instead
I really hope this was her move, here. She had just settled into a character that had room to grow. She came with a really cheesy gimmick; dancing Aussie chick who had a goofy accent and buddied up with Santino. Fans enjoyed it for what it was, but there was no future in that.
So when Paige, and then especially the 4 Horse Women started passing her by, she became bitter.
She was kinda like a female twist on HHH right before DX when he brought in Chyna as this weird Dominatrix/BodyBuilder/BodyGuard hybrid and slowly started drifting away from that limp-wristed, fluffy robed blue-blood shyt. Before we knew it we had fully defined heel HHH, with iron crosses and skulls on his gear, coming out to metal songs.
Emma changed her look. Darker blonde hair, cooler music, no dancing, leather gloves and aviators. Had the bytchy bodybuilder sidekick that everyone hated. It could've worked. When she returned from injury all they had to do was use Emma to steal back Dana from Charlotte to screw Charlotte out of the title against Sasha or Bayley and boom, you've created a new tweener character that can be either heel/face depending on who they're facing.
Instead they suspended Eva and try to pass her vapid, model-who-can't-wrestle gimmick to Emma, not realizing the only reason Eva had that gimmick is because that's kinda who she is.
WWE has to eventually learn from shyt like this and the peak-Roman sympathetic babyface push days and stop trying to force wrestlers into changing their character when the old one was working fine.
