I'm a little confused. You want to increase the size of / on the live 
install boot image? Pretty sure the answer is, "You don't." That's a 
temporary environment set up out of available RAM. If you want to 
continue to run off USB stick and not do an install onto your hard disk, 
I suppose I might see if doing an install to (say) a 64-GB USB stick 
might do the job, and then you could boot off of that, instead.

Of course, that assumes I got your intent correctly.
