Way to thick if you mean 1/4 inch per side should be less then half that, that will also not alow for flex if they are so thick.
The swoop at the pivot end is going the wrong direction, it is going to be in the way when you are stropping and honing..
The Wedge end is going to be a tight fit, it is possible but getting the "Wedge" in that short a space is going to be hard
