Neither of those will work because they clamp to a 1" diameter tube - the steerer - not the stem.
How about shortening the heat tube? Makes the steerer effectively longer. Almost any head tube can be shortened by the 1.5 to 2 mm you need to use an old (thin) steel Mafac hanger.
Good "pro" bike shops used to have the special cutter needed to shorten the head tube while keeping it parallel. Not sure if such expertise & tooling is rare or common in bike shops these days, but most any custom framebuilder can do it for sure.
