Your event is over, but you're wondering if you can still sell all-access passes for the replays.

An inactive event (i.e. an event that is still available to the public for the purpose of watching replays but is closed to new registrations) can still be charged after you close registrations.

However, you can only charge existing attendees. If you want to keep selling all-access passes to new attendees, then the event would need to keep registrations open and thus, it would be an active event.
