Thanks a lot for bringing this up and offering your help. Right now we still need to finish the design of the E1 transceiver part.
After that, there is room for evaluating different options of using it, both using a pure 'software defined E1' approach using a microcontroller and doing all the mux/demux/HDLC in software - as well as for an approach with some programmable logic involved.
That kind of experimentation doesn't really need a new board, as you can just connect the osmo-e1-xcvr via SPI/SSC to e.g. your favorite microcontroller.
If you're happy to work on that, e.g. to create a 'software defined E1' implementation, you're most welcome. I can send you either a populated PCB or a component kit + pcb to solder it yourself.
Design of a new board with integrated microcontroller is premature at this point. we first have to make it working as a wired-up prototype...
