That's already how this works, basically. You have to keep paying a fee to keep your patent, and the fees increase with each year of the patent.
The fees are fixed, but the effect is pretty similar to what you describe.
In some jurisdictions you get a discount on the fees if you declare that you are open to licence out your patent. Then everyone can use your invention without having to ask for permission,as long as they pay the license fee.
EDIT: I looked it up, in Germany (§ 23 PatG) the patent office can set the licence fees that others have to pay, so you can't play games by just setting the fee to a trillion euros.
