here are some ideas top of my head
>burnout writer who becomes a pro wrestler to look for a new spark, has moments where he gets annoyed during the match and starts shouting “I CANT WORK LIKE THIS”
>warlock gimmick, similar to the undertaker except even more cheesy, in vignettes he is always with a cauldron, shit like how he uses his opponents essence for potions and drink them to feel their strengths and weaknesses, comes out wearing a ragged coat, a top hat, and Sweeney Todd dyed hair
>guy who just vibes, has match types like loser gets a tattoo and he loses, trades in his MITB briefcase for a new boat, basically Jimmy Buffett the gimmick
>X-Files type gimmick for a tag team, who constantly try to uncover some conspiracy but never manage to, kinda like the Fashion Files was with Breezango
>Mick Dundee gimmick except the wrestler gets everything wrong about Australian wildlife, mixes up Australia with Austria etc
