Missed opportunity, doing a Charlie's Angels-Men in Black team up

Remember before what would become Men in Black: International came out (and in its own right, tanked at the box office) there were rumors about a Men in Black-21 Jump Street cross-over movie? I wonder what would've happened had Sony tried their hand at having Charlie's Angels get involved with the extraterrestrial. I don't know how the story would work but it's well worth a stab at something that had never been done with the Charlie's Angels property at that point. Or even crazier, instead of that all female reboot of Ghostbusters that Paul Feig directed, what if Charlie's Angels somehow crossed over into the Ghostbusters universe?
