The OFDM receiver is geared towards packetized data. It might work, but 
you'd need:
- A synchronization algorithm
- A better equalizer
- A definition for the packet format.

I would consider these things above rookie-level, but that's not to 
discourage you from trying :)
Also, there are many projects out there for digital radio. There's 
gr-drm (not sure if it includes a full rx, though) and I thought there's 
a GNU Radio DAB rx out there (ask the Googles).
And DVB-T is not *that* different, and we have GNU Radio codes for that, 
too.

Transitioning to the new version should be simple if you're just using 
stock blocks. There's a wiki page on the transition which will help you 
porting.
