Yes. A typical peak-time Horsham stopper can have SDO in use at stations such as (or all of) Littlehaven, Faygate, Ifield, Salfords, Earlswood, Norwood Junction and New Cross Gate. Of these, only Faygate and, at various times, Salfords could be considered quiet. At Ifield (and Faygate), you regularly have just the front 5 of 12 coaches open. At Littlehaven, anything over 8 coaches will probably obstruct Rusper Road LC on the Down.
Another route which has demonstrated this can work - without major delays usually occurring - on the GTR network is the Uckfield Line. Soon this will be almost irrelevant, but up until the middle of this summer you will still have SDO at an admittedly decreasing number of stations from Edenbridge Town to Buxted, including front 4 of 8 with no corridor connection between coaches 4 and 5 at Buxted, and SDO 5 at Edenbridge Town at all places.
