I can confirm the face plate bolts are m4 12mm items.
Very hard to find in torx and for the record the Toronto cycles m4 Allen's are pretty soft.

Have you guys considered drilling the center of the Ti bolts? I mean after all this is WW

Yes, and in some applications, a small capsule filled with compressed angels farts is installed to lighten it even further.

Seriously though, check out the work done to lighten the newer Extralite stem bolts. That's some attention to detail:

The four M4 bolts together weigh 3g.

To drill them would require a very fine bit, and not saving even a gram. But hey, you'd probably be the first!

Even if it saves 1/2 a gram. its a free 1/2 a gram

If it were me, I would do it on a lathe.

FYI, this is where I found my replacement bolts for my old extralite stem:

It looks as if they don't have them in 12 or 15mm length (it would be the TSHCS), but you could always get 20mm ones and cut them down to size.

Good to know. I ordered the standard M5 "stem bolts" and found there is a bit of play with allen head. Actually thought they may have been ASE rather than Metric, but they are indeed Metric. Just a bit sloppy.
