I would think Google would consider this black-hat SEO (cloaking) and you could get a penalty applied if they picked up on it.
But if you want to go ahead, the cloaking forum [webmasterworld.com...] might be your best bet.
A better option would be just to scrape a snippet and then point to the site you got it from for the full review as it sounds like you don't actually have the rights to the material in the first place.
