how about:
- unsoldering the factory part.
- soldering a 8 pin ?0.05"? pitch connector it its place
- soldering a mating 8 pin connector to any chip you want to use
- maybe add pushpins for easyer handling.

i did not yet look for the right connectors but they mus be out there...
i  would start lloking at smd connector for connecting 2 parrallel pcb's
