I hear they also make nice boat anchors.

No.
The camera shutter and leaf shutter must together be accurate or the overall exposure will be out. The sole purpose of a leaf shutter is higher syncronisation with flash; it will not guarantee any correct exposure if there is a fault with the shutter on the camera side; in fact, the camera may not fire at all.
