Thanks guys! Of course that would do the trick, why didn't I think of that.
As for which mics work for this application, you should look at Small Diaphragm Condensor mics and a (matched) stereo pair would be very preferable. I got a stereo pair of Gefell (old Neumann) M300s and they sound really good!

Here you see some pictures of the Gefell M300s in ORTF stereo setup

"Gefell M300 pencil begins with a 21mm gold evaporated Mylar diaphragm assembly with a temperature-constant ceramic housing. This technology was borrowed from Gefell's Test & Measurement division whereby when testing rockets for aerospace; it was found that temperature shift would cause metal expansion and performance shift. Ceramic components are proven to provide a more stable and uniform platform when the microphone is subjected to changing environmental conditions.

To reduce self-noise, an innovative DC to DC optical converter eliminates spurious electrical currents and noise typical of 48V phantom powering, thus providing a pure DC voltage to the capsule. This results in the quietest operation levels while delivering a full 80-volt plate voltage, for an unprecedent ed 147dB signal handling without the use of an input attenuation pad. This makes the M300 an ideal candidate for the demands of today's advanced analogue and digital recording formats."
