The preferred topology is to run your ADC at 100Msps, and make it a 
dual-channel ADC, and have it process baseband-signals only.

Gnu Radio itself doesn't have any limitation with respect to incoming 
bandwidth, per se.  But Gnu Radio executes on a real CPU,
  with real limitations.  In the end, it comes down to how much $$$ 
you're willing to throw at the problem, and how much
  hand-tuning you're willing to do.
