Hi,
This would definitely be possible, we would utilize the Custom identity integration via REST API to bring the values from the external database into Cvent upon registration, then we can determine pricing, allowance of registration etc within Cvent based on whatever criteria you deem fit.
The integration documentation can be found here.
For more information please reach out to your AM or CSA in order to ensure this integration is contracted or so that they may add it for you.
