Here is a wild idea
>Hololive: the movie
The chainsaw man movie had a budget of 4M and made 130M back, 4M sounds like the kind of money cover can save up mid term, we can assume all holofans would watch it so that's the floor and the ceiling would depend on how good the script is, I can see the potential for the kind of movie parents would want to bring their daugthers to the theater and if we include some cringy edgy rock in style anime fights maybe their sons too. A story about never giving up on your dreams, idol journey yada yada, maybe 4 or 5 song performances, animated by mappa, directed by Kojima, easiest cash grab in holo history.
>cons
Someone could graduate mid production and shit would have to be canned/rewritten.
More workload on the girls although it may be only 10 to 20 minutes of voice acting from them depending on the script.
The holostars question.
