Is it necessary that you see them all at the same time? If not, put some of them on a layer that you then make invisible.

If you work with linked files, you can speed up saving by turning off Create PDF Compatible File.

When you want to use the .ai file in other applications you need to turn it back on.

I doubt you will find a satisfying workflow for this. AI doesn't really have a proper proxy workflow and since it has a tendency to embed data when it realyl shouldn't because the linking system is kinda shot, substituting external images is not much of an option, either. AI really is a big old clunker in that regard and its poor memory handling doesn't help...
