Would these policies be from private companies? If so, are they free to price the policies as they choose, and free to reject any applications they want to reject? You say it is "guaranteed renewable," which presumably means a law that says that if they write the policy to begin with they can't cancel the policy (except for non-payment of course). But then are there controls on the pricing, or are they free to set the price of renewal to whatever they want (which would make any law about guaranteed renewal meaningless).
Curious about the details of what you have in mind here.
