#3 Carmella to WWE RAW
For the entirety of her WWE main roster career, Carmella has been a member of SmackDown. There aren't many other WWE stars that can boast about that. With a roster split almost every year since 2016, it is somewhat surprising that she hasn't switched brands even once.
For that reason, and the possibility that she would be an excellent addition to RAW's mid-card women's division, Mella should switch to RAW. She has feuded with the likes of Lynch, Flair, and Asuka while on SmackDown, but there's a lot of new blood on RAW now. Carmella hasn't faced Belair, Jax, Baszler, the IIconics, or Ruby Riott. If at least one of her, Riott, or Evans traded brands, those feuds would be both possible and fresh. Being in a relationship with Corey Graves would obviously be a slight roadblock in switching brands, but commentary teams could also change.
When Carmella returns, it would be a nice reset for her if she joined RAW instead of SmackDown. Carmella could even join forces with Jax to chase the Women's Tag Team titles. It could be a Shawn Michaels/Diesel situation and a different dynamic for the tag division. There are opportunities to be had all over the place, especially since the pandemic has forced a select few WWE stars to be featured.
