What if there was a bad joke in which Masahiro Sakurai had replaced Sora and the Kingdom Hearts universe with Leatherface and The Texas Chainsaw Massacre universe for final downloadable playable fighter and based universe for Super Smash Bros. Ultimate because The Texas Chainsaw Massacre was considered one of the the greatest horror films ever made according to film critics ever since 1974?
...Never happening. There is no reason it would happen, Smash is about games. Not movies, let alone horror movies. Leave Leatherface in Mortal Kombat X.
Nothing about this idea makes even the slightest bit of sense and I have no idea why you'd even suggest it.
