How about:

Increase number of groups. Limit groups to 75 cars - that is not a "crowded condition" at VIR. Ask the pace car driver to remember he has many cars of differing speeds behind him and he needs to hold a slow pace to keep them together.

Use Friday as an optional practice day. No qualifying.
Saturday, run one 20-minute qualifying session for an 8-lap Saturday race (all groups).
Sunday run one 12-lap race gridded by finishing position from Saturday's race.

That should loosen up the schedule and make everybody happy.

Works for me, but it's got to be done on an RE to RE basis.
