Hallo Andreas, with the current status of OFDM PHY code in GNU Radio I think it is definately worth a try.
The work I did on DAB was basically OFDM synchronization in one GNU Radio block. The code was more or less a hack, but it deepened my understanding of digital signal processing. Not as easy as in text books. :) I'll email the report to you separately. I wouldn't underestimate the complexities of the higher DAB layers, it has quite a protocol stack. But you should give it a try. If you need captured Mode I/II samples I can make them available for download.
