It's no longer an option just for the Elite.
You'll soon be able to remap the controllers on all Xbox One controllers, according to Xbox Gaming manager Mike Ybarra.
Remapping had only been previously confirmed for the Xbox One Elite controller, which retails at $150.

Button remapping lets players reassign the controls on their pad to their liking. It's a feature that came to the PS4 earlier this month.
