Weight won't be the issue with this ratio change as the HW for the 
most part carried by the hammerbutt center. The blow/dip could be, 
although you could certainly check this out in advance. (I actually 
haven't measured this, but the Yamaha verticals which have an upward 
sweep of the tenor strike line don't seem to have their dip bent out 
of shape by this.)
