To be Honest:
yes it all can be done with resolume. But when you need to have different screens at different locations with audio and other stuff going on i would also think about multiple players and a controll system
i.E.

https://pixera.one/de/hardware/pixera-mini
You also can set up multiple mini pc (intel nuc / zotac / etc)
The players would be close to the screens and the controll system can work via osc and a lan system.
When i understand this right its not nessesary to have the screens in perfekt sync (that make everything more easy)
