I'd be keen to make an FPGA based custom cpu board to go in, presuming they release port pinouts, timings and signalling details. This could be used for hardware laptop versions of legacy computers - Amiga, ST, Atari 800XL etc. Particularly if there is a slot for custom external ports to be exposed.
