Probably not.

I don't know whether this gesture would work for powerpc too, i.e.
how much brain it needs provided in HFS before it can deal with the
ISO 9660 filesystem for further progress.
But it's obviously the way how Matthew J. Garrett worked around the
lack of HFS+ support in genisoimage, back in 2012.

where he explained the layout produced by his modifications to program
isohybrid which added options --uefi and --mac.
Debian amd64 and i386 adopted the --uefi part of this layout.

Have a nice day :)
