Birmingham International is more likely to have a passenger flow at that time with it being an airport rather than housing. Housing I'd expect at 07:00 at the earliest.Probably as well to make the call at Rugby instead of BHI, then the service can use the Trent Valley route or go via Birmingham.
Down Highland passes at 22:22, the Up at 06:38 so that wouldn't be unreasonable, and there are LNWR connections in either direction (for Coventry & Birmingham and for Northampton & Milton Keynes) about twenty minutes before the evening pickups and twenty minutes after the morning setdowns
