Sure, but it would be impossible to manufacture such a device at
reasonable costs. The potential market is too limited.
Recently, we measured the frequency response of the MKH 800 for
frequencies of up to 125 kHz (the official plot supplied by
Sennheiser ends at 50 kHz):

To be honest, the extended frequency range of the MKH800 is achieved
to some extend by it's integrated compensation filter. Therefore,
the inherent noise floor is increased at frequencies beyond about 45
kHz. Also, the directionality increases at higher frequencies. The
official prices specified by Sennheiser are the same for both the
MKH 80 and the MKH 800 (but there might be differences at eBay).
Another, much cheaper solution would the electret microphone, that
employs a capsule by Emkay/Knowles. Unfortunately it's frequency
response is less flat (there are some similarities to the properties
of a parabola ;-)).
