BeetleBusters / JuiceBusters 

Ghost Busters x Beetlejuice

JuiceFiles

X-files x Beetlejuice

The Walking Juice

Walking Dead x Beetlejuice

Or, my personal fav, also stolen from a fanfic

Beetlejuice the movie x Beetlejuice the Musical, where the crackhead energy, definitely evil, maybe a little rapey movie Beetlejuice swaps places with the mostly harmless, sadboi, less evil but can def throw down musical Beetlejuice.
