The SCI0 games often had RESOURCE.001, RESOURCE.002, etc., which were never meant to be rejoined because of customers that had no HDD. Any duplicate resources needed for floppy play could be added to the separate resource volumes. By the time you get to the SCI1+ games the resource files usually were named RESOURCE.P0, RESOURCE.P02, etc. and would be concatenated into one RESOURCE.000.
Another problem that you may encounter is that some resources may be compressed and the original installer will decompress/extract them.
This something

This something I have looked into quite a bit over the last few years. I have been analyzing various installers to develop my new installers, Mostly Sierra and Sierra Family, but some non-Sierra installers, too.
