Without a middle connector, it basically becomes 2 one way tickets and re-ticketed and priced as such. You don't even have to call to do this. You can just cancel the whole multi-itinerary trip online and rebook the 2 one ways with the credits you get back.
Sure, but the two segments OP wants to keep will reprice.

For purposes of OP's question, it doesn't matter. The bottom line is you can't just cancel the middle segment and keep the other two without refaring.
