Now, for a theatre for a one off concert/? Yeah, that's very useful.
If Phase wanted to run an event on their own, here is what I would do: I would rent a room 1000-2000 seats adjacent to one of these cons actively going on (AX, NYC, OffKai) and do a full 27 talent concert/event for one night. Vtuber fans will already be in town, so it will be an easier sell to them to fly there and buy a ticket.
This happens in wrestling where on WrestleMania weekend, other companies will run shows because wrestling fans are in town.
