I thought about this. I think it would be incredibly difficult to pull of. Doing that means that effectively you have +2 different ways to interview candidates. Ensuring consistency, fairness and a good candidate experience with one standard process is already hard enough. I suspect you'd have a really difficult time running this process successfully. Also, inevitably some candidates would find it unfair, and complain about the option the didn't choose.
