If Hans could be encouraged to spin more boards or release the design files then this could be a possibility.

If I could order two boards to bump the count upwards I would, but what would I do the the second one

The latest Flash5 programmer is about $51 from DigiKey, which would take care of the programming part. It would not be difficult to get some boards made if the Gerber files were available. That just leaves assembly. Other than the FPGA, the board looks pretty sparse from the pictures I've seen. Are there parts on the other side of the board (other than headers)?

You could offer your services to assemble the board for someone without the soldering skills.

The FPGA is a VQFP packaged part under the bezel on the top side of the board. The pictures you've seen are of the bottom side of the board with the FRAM device(s), like these,

For the experienced DIY'ers you can solder the SMT parts on a stove with a frying pan.

The tricky part is flipping the board like a pancake for those double-sided boards. It's all in the wrist.
