Assuming you can drill a hole in the thing without causing massive injuries
to yourself (i.e. it probably still has +/- 1000psi of pressure and as the
metal gets thinner, there is a high risk of shrapnel being ejected...),
most valves  used on tires are only designed to hold <100 psi.

Tires on racing road bikes are sometimes pumped to 120 psi, but a valve
that holds 2000psi would have to be very hefty, and very well attached. For
example, the biggest danger on diving tanks is the valve breaking off,
which can easily shoot through the side of a car trunk.

Personnaly, I don't think this is a good idea.  Besides, the bombs are not
that expensive, I have a Mazda RX-7 with a leaky ABS unit, to replace it
costs +/- $3000, and the air pump (part of the emissions crap) is $800 if
it ever goes.

That said, you should never pay whatever Audi's list price is on anything,
esp. the bomb.
