I can use syslinux/isolinux to boot different ramdisks and floppy disks images fine on a single CD-ROM disk. But I want to use syslinux/isolinux to boot different bootable iso images from a single CDROM disk.

There is no reasonable way to do this. If the .iso image uses
emulation, one could extract the emulation image and invoke it... but
90% of BIOSes don't support this operation correctly (try the .img image
support and you'll find out.) For no-emulation booting, you're SOL --
it would require an offset operation in the BIOS.
Furthermore, most .iso images will sooner or later load a device driver
and talk to the CD-ROM directly, which will break if the CD-ROM isn't
the one you really expect...
