Sooo.. I did manage to get all versions on 1 usb.

se the gimagex list.png
Heres how:
Open the attached AIO manual.txt
and download the createaio.bat
follow the manual and it should work.
IF you get the error where it comes up blank when you have to choose the edition to install
then open the install.wim with GIMAGEX.exe and go to the Change tab and browse for source wim and select the image number (in my case both enterprises)
Put a Name and description on them and pres Change button.
That should make it work
