How difficult would it be to mod the drive's firmware to be able to do this..??

If you were to spend years coding firmare, etc you could eventualy manage to access the RAM cache of the HDD PCB somehow and use it to store data but then what ? Whould you spend some more years on another diferent model ? By the time you did manage to get one or 2 PCBs to allow you to access the RAM to store data as a virtual RAM disk the capacity of that RAM and the time spent on the project would make this absurd and not viable/reliable.
Just buy some extra RAM modules and create a virtual RAM disk. Forget about that idea.
If you do want to do something with those damaged HDDs just sell them on eBay for parts or sell the PCBs for people needing them to attempt data recovery ...

The only thing needed is that you open up the case, and connect the 2 SAFE-mode pins, since you want this permanently you could solder them together or bridge them with some conductive material. With the 250GB variant you get a 400 MB SATA disk that is directly representing the DRAM on the SSD. With the larger variants you might get more, I haven't tried that yet.
You can find more information about the EVO840 here:

But if you are worried about power loss, perhaps a UPS system to supply the whole PC with power might be more interesting?
