Yes, that should work - but if you are putting several disks on the same large
usb drive you would want to add another top level directory. Also if you ever
want to restore this to a bootable drive you'll need to create a matching disk
layout and re-install grub. Clonezilla would have done that for you with either
windows or linux targets, but at the expense of not being able to read the files
in the stored image.
If you aren't too concerned about making a bootable copy you could have just run
rsync from the running machines with either a local usb target or a remote
destination via ssh.
