How to image a UEFI Win8 computer with stand alone USB

I have Windows 8 computers running UEFI with safe boot.

I created a bootable, stand alone USB with the bootwiz to take backups with them.

With UEFI mode enabled the computers will not boot to the USB.

When enabling legacy mode I can boot to the USB.

If I take an image of one of these computers in legacy mode, will I be able to apply that image to another computer or back to the same computer?

Will I be able to do something like:

1. Take image in legacy mode
2. Enabled legacy mode on a Win 8 computer (that was using UEFI and safeboot).
3. Apply the image to that computer.
4. Reenable UEFI mode on that commputer

Will this work? How do I image UEFI safe boot computers with the bootable USB.
