What's the purpose of the mod? You lost your can opener and gained maybe (?) a better flathead driver.
Think OP is attempting to make the "Technician's Screwdriver" that is found on some rare pioneers and is worth a ton.
Depending on how the tip is finished I think it will work pretty well.
As to losing the can opener... well, for me anyway, it is my least used tool on the Pioneer, unless you count its use as a semi-decent Phillips drivers.
