Interesting idea.If that vise has removable jaws I'd make new ones.
My main vise was made in Poland with a sliding rear hand that slides on a
dovetail with adjustable gibbs.It is on the 3rd set of tool steel jaws.
Another thing I have done on milling machine vises is to make quick
detach jaws mounted on precision dowel pins for different jobs as
needed.These can be used to establish fast angles and other special
operations.
