I have the world best question

My greens average between 50-80% Poa, and the rest is Bent (and a mixture of several varieties). I have been trying to get the ratio of Bent higher but with little success. So I am thinking of just let the Poa become the main grass, and kill the Bent,,,,yes I said kill the bent!! With this being said, and I can't believe that I said it, does anyone have any ideas how to slowing eliminate Bent grass from Poa? I feel that if I have 100% poa greens I will have a smother and faster putting surface and I can cut of the expense of using Cutless and other products to control the poa. Is this a really crazy idea or is it possible that someone else has done this? Or maybe its time to retire.
