Asterisk GSM channel driver?

I have seen, that there are channel driver for the DECT project, where you
can connect your DECT handset to the Asterisk PBX. There is also somehow a
possibility to connect a mobile GSM phone via openBSC and asterisk.
But has somebody thought about just connecting the osmocombb mobile phone
(which is connected to a public mobile network [or openBSC]) to asterisk?
I would think of making a call through a channel driver, osmocombb is
doing a call like "call ms number", but instead of using mike and speaker
asterisk would send the already in GSM-codec modulated voice data through
the serial port (maybe it would needed to use the non-standard USB-TTL
version to handle full duplex GSM speech). And layer1 of osmocombb could
send that nearly untouched on the air. For incoming calls this could be
similar + signalling the call through the channel driver.
Has somebody already thought of that? Would that be a achieveable task or
is it technically impossible?
