It will make it worse.
Shin bang is caused by the opposite thing that you think. It isn't your shins slamming against the front of your boot... it is the act of landing backseat and making tears in the muscles in your legs due to stretching in the wrong direction. (more scientific and/or correct explanation is welcome)
I absolutely guarantee you that if you start making sure that you don't land backseat so much on your jumps, your shinbang will go away in a heartbeat. Like 99% of the time, this is the cause.
Also, if you're having troubles landing back seat because you come out of your rotations always slightly rotated back... this is almost always caused by your pop off the jump. Good strong pop will correct that in a jiffy. Doesn't apply if you're carving off the takeoff so much, but if you're doing that you're fucking with your axis and slightly different rules apply.
But seriously... the best cure ever for shin bang is to have a better pop off the jump. If you land in the back seat, just fall... because if you didn't stomp it you didn't land it anyways.
