How to reduce the size of the System map with Resedit?

I'm running a minimal System 7.0.1 on a 800K disk for my Plus. I would like to reduce the system map even further so I can put more on the disk. Is there anybody who knows what kind of files I can remove without damaging the system file? Maybe graphics, help files, etc. A 50K or 100K reducement would be great.

Any help is welcome. It must be possibe. Yhe installation system map is only 530K or so..but if I use that map it complains about missing scripts an stops.
