I think this is a great idea. You don't even have to market it like that: just have a very simple sign up form for requesting a trial. The only "requirement" would be a short discussion with a representative from your end where the customer explains why they want the trail. Market it as a positive (free trial!) and not a negative (if you don't want to give us your CC info...) and you'll have human psychology in your favor. You also get insight into your users' use cases for free.
