While I haven't tested it, you can assign multiple of any ZoneHVAC system (including ZoneHVAC:IdealLoadsAirSystem) to a thermal zone. You should be able to set availability schedules for each IdealLoadsAirSystem such that the one with unlimited capacity is only available on the weekdays and the other with limited capacity is only available on the weekends. You'll also want the ZoneHVAC:EquipmentList to list both pieces of equipment and can use the SequentialLoad load distribution scheme.
