Default Can I safely drill through Chromoplastic?

I got some lovely SKS fenders for my tour/commute rig recently and
discovered a compatibility problem with my frame. Since it's set up for
cantilever brakes, the seatstay bridge is not an actual brake bridge:
its hole, instead of being roughly horizontally oriented, faces the
dropouts and is threaded for a 5mm bolt, to allow fenders to attach
directly to it.

Problem is, the fenders don't have a hole in this region, instead
coming with an angled bracket that's supposed to attach to the brake
hole. For right now, I have this bracket bent around the bridge, but
since the bracket's not very long, it sometimes pops off, giving the
fender room to wiggle and occasionally lean on the tire.

Hence, the question in the subject line. I believe the "Chromoplastic
is simply metal with a plastic laminate on each side. So is the
laminate prone to some sort of horrible cracking/shattering requiring
some ultra-specific drilling technique, or can I just have a go at it?
