In SFO I'd probably go so far as to tell them to use NAV for the intercept for a while until established, then swap over to LOC/GS when convenient. You're PIC, so you're allowed to do it (especially if it's in the interest of safety). Just my two cents.

I can admit I did this a time or two, Ive watched a few CA's do it also. Its not pretty in either case.
IMO I think the LNAV/FPA double capture by around the 4miles/FAF works awesome. Especially if your gonna capture the course beyond a conservative 15 degree intercept.
