I don't think this is possible as you can't have 2 systems serving 1 space in eQUEST.
I think you'd need to run the simulation twice, once with both fans combined, and once with just the smaller system. Then you'll need to piece the data together.
Or you could generate a custom fan curve that mimics the performance of the system, but this might cause problems in low flow conditions for the 6 months of the year where both fans are running.
Good luck with this challenging problem.
