A sheet of 400 grit sandpaper will do the job in a few minutes. Tape the sandpaper flat on a countertop with one edge flush with the edge of the countertop. Then can either thin only the top part of the bridge by holding the legs out over the edge, or thin the whole thing by laying the bridge flat on the sandpaper. Or some combination.
Used to do this back in the "olden days" when thin bridges were in vogue. Some used bridges that almost came to a point at the top (although the bottom of the string grooves were a little wider).
Part of the change in sound is due to thinning the top of the bridge, and part is due to reducing the overall weight of the bridge. In my experience, the change in weight is the larger effect.
Hope this helps.

Endorse all of the above. Thin them yourself, that's what sandpaper is for. Or ask Mike Smith or Tim Purcell, they'll make anything you want.
One recommendation. If you've never taken sandpaper to a bridge before, practice once on a cheapie chinese bridge,or other throwaway, before you go after a nicer one.
I concur with the sanding option. I have experimented with sanding bridges thinner to see what the audible result it. I used to do it with sandpaper on a flat surface but now use my belt sander. I monitor the thickness based upon the weight of the bridge. I have a mini scale which I weigh all my bridges and write the weight on one of the feet underside along with the height.
