There's a notable lack of horror characters, so the obvious choice would be Leon Kennedy.
>appeared on an Nintendo platform (GC, Wii, Switch)
>popular character from a popular series
>popular in the East and the West
>decent move set (tankier Snake)
>goofy enough for a Smash appearance
>Spencer Mansion stage
Honestly, the only downside would be the lack of any standout music.
