Not sure why you'd be mixing those two systems for an appendix G model? As of 90.1-2013 your baseline system type depends on your climate zone. Prior to that, it generally depended on the buildings heat source. If gas heat was available, system 7 would be your baseline for the entire building (with some rare exceptions that I don't want to get into). If this is just an academic exercise, the chilled/condensing water rules for systems 7 & 8 are identical so you could share the condenser loop if you wanted.
