theoretically possible, yes.

The biggest challenges, from my point of view, are:
* using phones that don't use secure/authenticated boot for the BBP, or
those where the certificates have leaked and/or exploits are known
* finding significant enough amount of leaked sources or documentation
and/or doing the reverse engineering required to understand how to talk
to the DSP and/or related peripherals
* finding the time to work on the protocol stack beyond classic 2G which
is currently implemented in OsmocomBB.

Harald
