"I know he makes his own choices, but it can't be his fault she's a cock-block, which I think is what is pissing me off the most about her now."
Of course shes a cock block, shes a woman, and she is your buddies girlfriend.
"hang out with him more, hopefully pissing her off, which she'll take out on him after I leave, and maybe drive that wedge in a little."
Seriously? She will just emotionally beat him down.
"I'll have a few girls ready to hang out with the two of us, add in a few drinks and hopefully he bangs one of them."
Not by the looks of it, he will go home and bang his girlfriend.
"If all this works, I'll write a book about it, as it seems a lot of guys have lost friends this way."
I wouldn't read it based on this strategy. You need to be honest with the dude, straight up, call him out on dating a nasty pirate hooker who is castrating him. Its really a no brainer, this is like a bro-intervention, or brontervention.
