Generally do-able, but you need to use a bit of caution.
Essentially, you would inject the composite video in just after the video detector stage. Couple it in through a capacitor, to keep any DC present from damaging your DVD player or whatever.
Unless you use some kind of isolation circuitry in the video line (wideband transformer or optical isolator), DO NOT attempt this modification on a series string "AC/DC" type chassis.
