Legend
Yes, I edited it out. Sorry.
I seem to recall some source indicating that Vader couldn't use Force lightning because of his cybernetic hands, but that might be Legends material now. Probably some novel or other that I read ages ago.
Anyway, my point was simply that being a cyborg seems to be a disadvantage for Vader, so I'm not sure why you'd want to deliberately make a Force-sensitive cyborg.
On a side note, I'd be interested to note the extent and function of Fennec's cybernetic parts. It looks like her intestines have been replaced by mechanical bits. I wonder if that means she no longer has to eat or drink, or if there are machine parts that do what her intestines used to do. Just idle curiosity at this point.
I can answer that but it's legends based.
Vader still can't use force lightning in new canon except in the spiritual realm.
