Ouch, as they're not mounted by default by any kernel anyway but require
device driver (UIDE.SYS) and an installable filesystem driver

1 : boot from CD, use as LiveCD (with hidden harddisks)
2 : boot from CD, use as InstallCD (visible harddisks)
3 : boot from CD, boot ISO from CD, use as LiveCD (hidden hdds)
4 : boot from CD, boot ISO from CD, use as InstallCD (visible hdds)
Your suggestion allows  but prevents  as the harddisk gets hidden
during ISO loading time.  is not possible as hiding harddisk also
hides CD, according to your comments.

See above. Duplicating ISO could be possible but isn't my favourite option.
My last resort is relying on the DOS PCI IDE/SATA CD-driver called UIDE
by Jack R Ellis, but that's limited to PCI IDE/SATA thus instead of
ELTORITO.SYS 's controller-independent hooking into non-emulation CDs on
for example USB CD drives.
