No you can't just add on segments and expect it price the same as DL uses married segment logic on awards. Linking is just a notation, you can't combine PNR's. Note that LHR-SFO flight is operated by VS, not DL. With AF/KL/VS/DL relationship I suspect you would be protected in the event of delays, but I don't think there is anything that explicitly guarantees it.
