Running cables through alunimum bars is a singularly bad idea. It's not so much where they go in as
that they inevitably have to come out. That's usually near the stem where stresses are large and the
holes provide a classic stress-riser.
Otherwise sensible people will explain to you sincerely that _their_ drilled bars are safe because
they filed the hole edges smooth. OK, that makes it slightly safer, as much as pouring gasoline
while smoking a _filtered_ cigarette.
DiaCompe's classic 188 reverse lever was originally designed for use with a schoolboy's steel
handlebar. Lightweight triathlon bars really do snap off when drilled to exit those cables.
Back to your direct question. Why not exit the lever normally and just secure the casing along the
underside of the bar? The exit angle is not so hot on a straight aero bar so leave a small loop of
casing at the lever (rather than trying to tape it down flush) to avoid kinking the casing.
It is certainly _possible_ to drill a hole behind the lever body. It will look really cool, until
you faceplant with the piece of handlebar still in hand.
