wii remote buttons switching

I’m in the development process of a shooting game programmed in flash AS 3.0. intended to be played in the Opera-based internet browser. The problem is in the wii remote. While in the internet browser the A button is the only active button and all shotgun-like accessory for the wii remote use the B button when pulling the trigger.

I was wondering if there is any way to physically switch the A button to the B place.

Any help or advise will be greatly appreciated.
