Well that ble_epo_offline.bin file is just a bunch of CASIC MSG-GPSEPH/MSG-GPSION/MSG-GPSUTC messages with a text header. So there's nothing too tricky about it. If the chip accepts it we could even build it ourselves using data from another service (e.g. supl.google.com) or pulled from another gps unit.
