There is no way to combine those more?

Reasonable, yes.  But possible?  The question is, "Can it fit in ram?" 
and "Can it fit in the disk image?"  Your config file will be giant, and 
the disk image is not...  The only thing to do is to try with 100, and 
see the difference.  You can check what it does to your disk with the 
hidden status.php page.
