Handle bars don't put much of a load on the triple, compared to the fork legs.
Looking at your second E Bay photo, it looks like there are already two screw holes out near the tube clamps....drilling two more holes in the thickest part of the triple clamp, to accomodate two more holes to give you four mounting points for the plate shouldn't be too much load.
