Turn Tom Ford 207s into 108s

Has anyone thought about or tried removing the additional piece of metal on the 207s to make them more like the 108s. I have a pair of 108s in gunmetal and grey lenses and I love the look but the temples are slightly short and I know the 207s fit better (longer temple). Plus I could afford to buy a pair in the correct color combination.

Anyone broke a pair and noticed if the metal is plated or solid through.
