Belloq, very good ideas here. Looking forward to seeing the clips.
As for the Mutt swinging on the vine bit, have you seen the edit that does away with the vines all together. In it, Mutt leaps into the jeep with the skull, the skull falls into Ox's hands (using the clip from earlier in the scene) then Mutt falls onto the floorboard of the jeep next to Indy (where he originally landed after swinging from the vine). Works well.
