Generally, an agent will refuse to make this change. Your best bet is to change it after boarding SFO-DEN, assuming you don't have checked luggage. If you have checked luggage, this isn't particularly likely to work, although you could still ask.

Only if the agent is willing to make a pretty substantive break from protocol and introduce a stopover on a domestic fare. There haven't been a lot of reports of success.
