Cloning ROM to Other Touches

[need bb]

My entire family has Touches and I customized everyone's phone to have the programs and UI the same way (No one liked the stock Sprint). I recently upgraded my phone to one of the M2D kitchens and my family members want to be also upgraded. Can I use Sprite Backup to make an image of the rom and then restore it on their phones so I don't have to reflash their's and then load all the programs? If not what would the best way to clone my phone to their's?

Thanks
