Me too, sorry, showing my theatre kid side but it would be the first thing on my mind. And fwiw I also know a ton of references from my parents’ generation, some of which I’ve never even seen the film for or whatever, I have just absorbed them by osmosis 
I can totally see it working for your vibe, though, and I don’t think it’s unusable or anything, just that the LSOH reference is a strong one for many people.
