[lubuntu-users] Is it possible to 'multi boot' ISO's with MKUSB?

[scrooyahoo at riseup.net]

I'm looking into MKUSB and OBI.

I see OBI can pick tar-balls stored on a stick. But is it also possible 
to work with multiple ISO's?

Would be nice to have 1 stick that can load:
32 bit
64 bit
pae
and eventually also the PPC

And also to make a stick with all 32 or 64 bit *buntu's side by side.

Specially now that 8GB is about the smallest stick size thats still 
available in stores.

This would it make it less of a hassle to try a few distros.

I now have 4 Sticks in use for Lubuntu 16.04 64, 32, and alternate 64 
and 32bit
that puts about 28GB doing nothing.

I have tried 2 multiboot options i could find but for some reason only 
one of those partially works.

OBI looks like a good solution, but most distro's sit in a ISO.
