A lifeline idea that I once had

I had this idea for a lifeline a while back. It would be an alternative to 50:50 or double dip with a slightly different kind of suspense. It's essentially the same as double dip I think but executed in a different way. I tentatively named it "Elimination" but you guys probably have a lot better ideas then me. I'm not sure how well it could work in a game, what do you think?

Here's how I think it would work. Let's say there was a question where the correct answer was C. The contestant is torn between A and C, so they decide to use their elimination lifeline. They would name the answers A and C. The answer A would be eliminated. The contestant has already ruled out B and D so C is their final answer. But they can't necessarily trust this! Let's say there was another question with C as the answer. A contestant doesn't think C is the answer and they also rule out D. They decide to use the lifeline and name the answers A and B. The computer randomly picks which answer between A and B to eliminate. Let's say it eliminates B. Then the contestant would make A their final answer and get it wrong. I don't think there would be any advantages over double dip, but it kind of adds more unpredictability.

Let me know if you need me to clarify it and if you think it's a good idea or not
