Then, I had an idea. The brake pad holders themselves weigh hardly a tad. So no matter the % difference in weight between different materials, the absolute weight wouldn't vary much.
And I happen to have a set of generic brake pad holders that weigh a total of 68.6g.

Took one apart to get an idea of the distribution of mass:
I'm missing a photo of the brake pad holder itself, which weighs 6.7g on its own. (~17.2g total for one brake pad). By estimation, I have a few tuning options:
1) Sanded brake pad holder
2) Cork pads
3) Nylon spacers
4) Aluminium stopper bolt
5) Aluminium mounting bolt (male)
6) Drilled slot on brake pad holder
I don't have an idea what the goal for the final weight is. Anywhere near the BTP w/ yellow SwissStop pads' 44g is nice. Meaning, I have to save 24.6g!
So, I proceeded with (1) first. I thought of dunking the whole pad holder into paint thinner first. But it didn't seem to have an effect. I can't explain why, to be frank. Anyway..., I might as well sand it all apart...

I kind of regretted my choice of weaponry after a while. To be honest, I never sanded stainless steel by hand before... I think I won't be doing it ever again, after - as well. So I thought of equipping a hacksaw instead...
Then I regretted it again... and decided to go back to the half-rounded file. I should use a dremel...
So... I ended up spending almost 1.5 hours sanding away with the flat surface. I spent another 30min or so just cleaning up as much of the remnants of the black coat in difficult corners with the half-rounded section.
And that's just one pad. (Then my sister pointed out that it was 2.30am and she needed to sleep - which she couldn't, hearing the sharp noises from the living room.)

Oh, and I ran out of 220 grit sandpaper. Got to buy some. ^^ I must take note not to overuse the sandpaper, otherwise the weight savings to cost ratio diminishes below getting a new set of BTP pads (129 euros excl shipping... uhhh...)!
