End Grain Cutting Board Out of Teak Butcher Block?

I'm a pre-beginner woodworker... I'm still in the tool buying period and coming up with "brilliant" ideas that may not work. Anyways, I'm going to have some extra teak butcher block countertop from Lumber Liquidators. And I though, this would save me a ton of steps when I make my first cutting board. Would this work? Will it last? Am I a genius? (I know the answer to this last one... my wife said hmm 😒) Anyways, what are your thoughts?
