set MembershipProvider properties (dynamically?)

Is it possible to set the MembershipProvider properties dynamically?

The properties such as minRequiredPasswordLength, maxInvalidPasswordAttempts, etc. should be available to be set by an Administrator of the web application without having to modify the machine.config.

Basically, I will have a "Settings" page where the Administrator can set these properties which would be stored in the database. I would like to be able to set those properties from the values in the database.

Thanks for any help you may provide!
